Brew: `brew update` fails to checkout tag

[m0ll3art]

If Homebrew was updated on Aug 10-11th 2016 and brew update always says Already up-to-date. you need to run: cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update.

Please follow the general troubleshooting steps first:

• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [x] If you're seeing permission errors tried running sudo chown -R $(whoami) $(brew --prefix)?
  I thought this -^ step is not needed anymore and root can own folder structure again? Is this still the case ?

Bug reports:

kind of regression bug for me :-(

Since a certain brew version, don't remember which one (AFAIR the version claiming root can own /usr/local/ again) i had troubles

$ brew update
fatal: Cannot update paths and switch to branch 'stable' at the same time.
Did you intend to checkout 'refs/tags/1.0.8' which can not be resolved as commit?
fatal: Needed a single revision
invalid upstream refs/tags/1.0.8
Already up-to-date.

before it was same message with version 1.0.9 .. I had a tag 1.0.9 in refs/tags/.I issued a git reset --hard to overwrite local version and it was ok . But now this bug comes back somehow ?

I do not make local changes to homebrew or whatever. I don't understand what's happening.

I also enable debugging see attached file

out.txt

thanks for your help

[m0ll3art]

forget to say that of course all brew commands are impacted

$ brew  install npm --with-openssl
fatal: Cannot update paths and switch to branch 'stable' at the same time.

[MikeMcQuaid]

Try to run cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update

[m0ll3art]

this is what I'm doing each time an issue like this happens. The question is now why this happens again after a few brew update went ok?

This will solved the issue now but I'm sure it will happen again in some weeks, since this is the third time I have to fix it.. as far as i can remember I did not had such issues in the past (with legacy-homebrew?) . Do you have any explanation? Did i do something wrong ?

[MikeMcQuaid]

What does cd "$(brew --repo)" && git tag --list output?

[MikeMcQuaid]

Closing due to no response. Will continue to answer questions, though.

[MikeMcQuaid]

What's your output after that from git tag --list? Does it include 1.1.0? Please paste your brew config and brew doctor output, thanks!

[m0ll3art]

yep now 1.1.0 is included also after brew update.

next my brew config output 👍

Ok, looks fixed. Post here again if it happens again. Thanks!

[CamJN]

I'm seeing this on one of my boxes too. I've previously had this problem, and temporarily fixed it with cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update but it comes back.

[MikeMcQuaid]

I'm seeing this on one of my boxes too.

This was a brew update bug that affected you if you updated in a certain window. We cannot fix the old version of brew update so there's nothing else we can do except post the workaround.

[CamJN]

Sorry, I mustn't be understanding you properly, why did the problem come back today if the brew update bug is fixed? And the tag the error refers to is in the list...

[MikeMcQuaid]

@CamJN You were "stuck" on an old branch/tag.

[m0ll3art]

I completely agree with @CamJN because since El Capitan on this MBP each new tag creates such an update message .. For me applying the workaround only solves the issue til the next tag .. Somehow weird .. But many thanks for your help

[m0ll3art]

I found some clues .. I should have began with that
here some status info

really weird ..

and here the remote

origin  https://github.com/Homebrew/brew.git (fetch)
origin  https://github.com/Homebrew/brew.git (push)

seems ok but

$ git status
On branch v1.0.6
nothing to commit, working tree clean`

$ brew --version
Homebrew 1.1.2-2-g0c82cce
Homebrew/homebrew-core (git revision c5f43; last commit 2016-12-01)

so really strange I'm missing the branch stable !! this branch is the one I have on another machine which seems to work ok

How to repair this mess without losing the installed software ?

[MikeMcQuaid]

How to repair this mess without losing the installed software ?

git checkout master; git branch --delete v1.0.1 v1.0.6; brew update --force

[m0ll3art]

this is exactly what I have done with -D instead of --delete because git claimed that those 2 branches were not fully merged. The --force update put me on tag v1.1.2 branch . Is this correct ? or will the next brew update again break the stability ?

[MikeMcQuaid]

You should be on a branch named stable or a branch named master. If not, run git branch -D v1.1.2; git fetch; git checkout master; git reset --hard origin/master; brew update --force. If you're still on the wrong branch after that: paste your brew config output in here.

[m0ll3art]

It seems that the brew update --force operates strangely on my config. This is the point I'm somehow not able to switch to stable ..

I manage to get back on master

$ brew update --force
fatal: Cannot update paths and switch to branch 'stable' at the same time.

At this point I'd probably recommend doing rm -rf /usr/local/Homebrew/.git and rerunning brew update.

0f529dae1043639058130092cf35e68d18907cb8 but what is the diff between commands ?

[MikeMcQuaid]

Same with both? Difference is there's something weird going on with your Git. What does git checkout --force -B stable refs/tags/1.1.2 output?

[MikeMcQuaid]

And also what does ls -lha stable refs/tags output?

[m0ll3art]

oups haven't see the filepath before . yep both are identical

out from git checkout .. on branch stable

[m0ll3art]

but brew update same message as usual .. FS is case sensitive I assume not an issue .. ?

[MikeMcQuaid]

Please provide the full output of all the commands requested so I can help.

[m0ll3art]

checkout --force -B stable refs/tags/1.1.2 -> Switched to a new branch 'stable'

[m0ll3art]

the rev-parse you already have

[MikeMcQuaid]

the rev-parse you already have

Was the output identical for both invocations?

ls -lha stable refs/tags

Just to confirm: is that in /usr/local/Homebrew/.git/refs/tags or /usr/local/Homebrew/refs/tags?

[m0ll3art]

yeah output identical and the former /usr/local/Homebrew/.git/refs/tags

[MikeMcQuaid]

Ok, so /usr/local/Homebrew/refs/tags doesn't exist? If so, I have no idea what to do now, sorry. It could be related to case-sensitivity.

[m0ll3art]

nope doesn’t exist . But it doesn't exist neither on my other MBP so surely not the problem .. The diff between both systems is the case-sensitivity of the FS but i cannot imagine this should an issue otherwise i would have some doubt about the nextgen brew ;-)

[m0ll3art]

but anyway thanks for your help

[MikeMcQuaid]

i cannot imagine this should an issue otherwise i would have some doubt about the nextgen brew ;-)

We don't do any testing or CI on case-sensitive filesystems so, although I also doubt it's an issue, they do seem correlated to me.

[m0ll3art]

perhaps as an OS X package manager, it would interesting to perform some CI and testing on case-sensitive FS since some of us are only using cs FS ..

[MikeMcQuaid]

@m0ll3art Alternatively, perhaps as an OS X user it would be sensible to use the default filesystem configuration 😉. We'd consider doing testing and CI if we had unlimited funds and time but sadly we have very limited of both 😭

[m0ll3art]

@MikeMcQuaid perhaps this article Linus Torvalds: Apple's HFS+ is probably the worst file system ever | CIO may help why I dislike HFS+ case-insensitivity and not mentioning security issues. But thanks for your advice

[MikeMcQuaid]

since problems are expected

We don't expect problems but, like everything brew doctor warns you about, there may be problems. In this case there's an issue that seems specific to you and your machine that could be related to case-sensitivity, Git configuration or something else. My guess was case-sensitivity but I don't know for sure and unfortunately I can't justify spending any more time on an issue that appears to be specific to a single user's machine.

For me case-sensitive should be the default FS and not the case-insensitive one

That's up to you but ultimately we defer to Apple's defaults and that's what we support because that's what 99% of people use. Again, you can use what you want but we may be unable to help debug issues. If you can figure them out yourself and submit fixes (not just warnings) we'll consider merging them. If you can't figure them out yourself I might make a gentle suggestion that you'd be better off using the defaults.

[m0ll3art]

that's what we support because that's what 99% of people use.

99% of the Mac Users are using case-insensitive FS .. This is a revelation to me and I feel so stupid now to belong to this 1% of the user using case-sensitive FS on my Mac. Of course you've done your fact checking .. Perhaps this would be worth a tweet ? The lead maintainer of Homebrew claims that 99% of the people are using HFS+ case-insensitive FS .. Hope @mxcl agreed with such a statement and also how you handled this issue ..

Thanks @MikeMcQuaid for your strong remarks and facilitating the discussion. I quit homebrew since I only represent 1% of 1% of the users and you will not be able to help me.

but we may be unable to help debug issues.

Please do not change anything so great .. sorry but I'm pi.. off

[MikeMcQuaid]

It's the default on macOS. Most users use the defaults (that applies to most software, too). brew doctor warns on output and I've read many thousands of brew doctors and very, very few have people using a case-sensitive OS.

Hope @mxcl agreed with such a statement and also how you handled this issue ..

I'm the lead maintainer of this project and I know @mxcl in person and he'd very likely agree with me that focusing on the 99% case is a better use of the project's time.

I quit homebrew since I only represent 1% of 1% of the users and you will not be able to help me.

I hope whatever you use instead works better for you, genuinely.

Please do not change anything so great .. sorry but I'm pi.. off

I'm sorry that it's frustrating but I you may need to appreciate a few things:

• I'm on vacation today and am spending most of it working on Homebrew. I'm not paid to do this.
• Homebrew has a bunch of open issues that are reproducible and affect multiple users using the default, supported configuration. I need to prioritise them over this.
• This project is provided to you for free and, as the BSD license states, as-is. Any support you receive is a bonus but not something you are entitled to have. In this case: I've spent a bunch of time on my evenings and weekends trying to help you and help figure out this issue and we've reached the end of my ability and time to solve this problem. That's frustrating for you because you're still affected by it but, again, there's nothing more I can do to help you here.

This stackoverflow post suggests creating a case-sensitive sparsebundle disk image for debugging case-sensitive issues with git. @m0ll3art if you can reproduce your error in this type of disk image and post instructions, then I'll try to reproduce it.

@MikeMcQuaid thanks for all you do for homebrew! Enjoy your vacation!

I have a normal case insensitive FS and the problem has returned with the new 1.1.3 tag. /usr/local/Homebrew/refs doesn't exist neither does /usr/local/Homebrew/stable (though /usr/local/Homebrew/.git/refs/tags does exist).

I'm going to hold off running git checkout --force -B stable refs/tags/1.1.4 just in case there is more info that I can provide.

[9130khz]

I've been watching this thread for a while now. I'm on a default FS as well and have been seeing the same issue. I thought i'd try fixing it by completely uninstalling and reinstalling brew, but a few days after reinstall i'm getting the fatal error with the new 1.1.4 tag as well.

[m0ll3art]

so i confirmed

installation a new completely new system case INSENSITIVE FS.. no further comment from my side

@m0ll3art As I said before:

• I'm on vacation today and am spending most of it working on Homebrew. I'm not paid to do this.
• Homebrew has a bunch of open issues that are reproducible and affect multiple users using the default, supported configuration. I need to prioritise them over this.

I realise you're frustrated and I did not say above it definitely was the case sensitive filesystem causing this but just that your unsupported configuration caused me to deprioritise this.

Can you confirm what had been done/configured on the completely new system before installing Homebrew?

[MikeMcQuaid]

@m0ll3art @CamJN and @9130khz: can I see your brew config, brew doctor and the full contents (bar any secrets) of your ~/.gitconfig files, env | grep -I git and alias | grep -I git output on any affected systems.

[CamJN]

@MikeMcQuaid sure thing:

[MikeMcQuaid]

@CamJN Great, thanks. Can you see if the issue goes away if you either:

• temporarily rename ~/.gitconfig to ~/.gitconfig.old
  or:
• brew install git
  and then run brew update for either? Thanks!

Also, what directory do you run these commands in, randomly, and what's the contents? Thanks!

[CamJN]

Sadly neither mv ~/.gitconfig{,.old} nor brew install git fixed it, still get:

fatal: Cannot update paths and switch to branch 'stable' at the same time.
Did you intend to checkout 'refs/tags/1.1.5' which can not be resolved as commit?
fatal: Needed a single revision
invalid upstream refs/tags/1.1.5

[MikeMcQuaid]

@CamJN Thanks for trying anyway. Directory contents?

[CamJN]

/usr/local contains these directories: Cellar, Frameworks, Homebrew, bin, etc, include, lib, opt, sbin, share, var

If you want a full recursive listing I'll have to put that in a gist, but I'm happy to do so.

[MikeMcQuaid]

Are you running it inside /usr/local itself or /usr/local/Homebrew or someone else? Can you confirm if /usr/local/.git exists by any chance?

[CamJN]

/usr/local/.git does not exist. I ran all the commands from my home dir, if that's what you mean. So here's the contents of that too:

@CamJN Assuming you can still reproduce: what does git tags --list and ls /usr/local/Homebrew/.git/refs/tags/ output? Trying to figure out if the tag just doesn't exist in Git yet or if it's a syntax error.

[CamJN]

camdennarzt@WALLE:/usr/local/Homebrew [stable L|✔] $  git tags --list ; ls /usr/local/Homebrew/.git/refs/tags/
git: 'tags' is not a git command. See 'git --help'.

I've been having this same issue, and decided to just try messing with git. I navigated to '/usr/local/Homebrew' and ran 'git pull origin master' with master being my only branch. Stuff got pulled down, and then I ran a 'brew update' and 'brew upgrade' and both worked properly without all of the previous 'fatal' issues.

So try that and see if it works for you as well. I do not yet know if the problem will come back again in the future (as it does with the previous fix).

[MikeMcQuaid]

Sorry for radio silence, been ill. I'll look into this over the Christmas vacation.

[CamJN]

No problem, just let me know whenever you need something checked/tested.

[itwars]

Hello,

I have the same issue:

fatal: Cannot update paths and switch to branch 'stable' at the same time.
Did you intend to checkout 'refs/tags/1.1.5' which can not be resolved as commit?
fatal: Needed a single revision
invalid upstream refs/tags/1.1.5
Updated 2 taps (caskroom/cask, homebrew/core).

Homebrew 1.1.5

This morning same with:

invalid upstream refs/tags/1.1.6

[brennan724]

Update on my comment from 18 days ago: the problem has now returned, with refs/tags/1.1.6. Brew doctor says that the system is ready to brew.

[djwbrown]

Same issue appeared for me a few days ago.
brew update
fatal: Cannot update paths and switch to branch 'stable' at the same time.
Did you intend to checkout 'refs/tags/1.1.6' which can not be resolved as commit?
fatal: Needed a single revision
invalid upstream refs/tags/1.1.6
Already up-to-date.

Resolved with:
cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update
Thanks for all your work @MikeMcQuaid!

[MikeMcQuaid]

If this affected you before it's still going to affect you. Unfortunately I'm still unable to get to the bottom of this issue.

[ilovezfs]

Can we please see the contents of /usr/local/Homebrew/.git/config ?

[djwbrown]

cat /usr/local/Homebrew/.git/config

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true

[itwars]

Again :

fatal: Cannot update paths and switch to branch 'stable' at the same time.
Did you intend to checkout 'refs/tags/1.1.7' which can not be resolved as commit?
fatal: Needed a single revision
invalid upstream refs/tags/1.1.7

It works after:

cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update

But back again ...

[ilovezfs]

It will happen every time there is a new tag until we figure out what is wrong.

[MikeMcQuaid]

If this does fail for you your brew config output immediately after the failure (and before running the git reset --hard) would be useful.

[MikeMcQuaid]

brew config HOMEBREW_VERSION: >1.1.0 (no git repository)

Is anyone else getting that output?

This is still a mystery to me. Next person who can reproduce it: can you rerun brew update --debug --verbose and stick your output in a Gist? CC @CamJN who has been pretty responsive here.

[CamJN]

I figured out the problem on my end, it turns out that one or more uses of grep were using my $GREP_OPTIONS envvar and breaking b/c I have color forced on. I'd changed that on my main box but hadn't synced my dotfiles to my other laptop in a while.

It might be worth doing an unset GREP_OPTIONS at the start of the script.

[9130khz]

Hey i've got color forced on for grep too. Nice find!

[MikeMcQuaid]

I've got export GREP_OPTIONS="--color=auto" which feels more sensible. This will be addressed by https://github.com/Homebrew/brew/issues/932 but in the mean time I'm going to make a rare exception and filter GREP_OPTIONS. Great work here @CamJN.
