• [x] have a problem with brew install (or upgrade, reinstall) a single, official formula (not cask)? If it's a general brew problem please file this issue at Homebrew/brew: https://github.com/Homebrew/brew/issues/new/choose. If it's a brew cask problem please file this issue at https://github.com/Homebrew/homebrew-cask/issues/new/choose.

• [x] ran brew update and can still reproduce the problem?
• [x] ran brew doctor, fixed all issues and can still reproduce the problem?
• [x] ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?

hub won't install under Linuxbrew due to a mismatch in bundler versions.
https://gist.github.com/liamdawson/257f4659a4e7493f5af16ff90a40cd7c

Reproduce by creating an Ubuntu/etc. virtual machine, and running brew install hub.

The process of installing the hub formula installs Ruby 2.6, which includes bundler as a default gem, so I suspect it's an issue borne of trying to use a different gem version in that environment.

I got the same OS (Ubuntu 18.10). But didn't have troubles with hub installation. See my gists maybe it helps you…

$ brew config
Homebrew Ruby: 2.3.7 => /opt/.linuxbrew/Homebrew/Library/Homebrew/vendor/portable-ruby/2.3.7/bin/ruby

Using system ruby2.6.0 from Brightbox's -t bionic PPA as rbenv shell's version OR ruby/2.6.0_1 from cellar as rbenv shell's version.
And when I rehashed environment and made

$ brew config
Homebrew Ruby: 2.6.0  (which pointed to brew's installed ruby 2.6.0_1)

I also could remove/install hub normally.
PS rbenv is a RVM analog

[liamdawson]

Yeah, weird, I just tried again and it built this time. Only thing I changed was logging into a Ubuntu instead of a Gnome session, and I doubt it's related. Maybe something changed in brew/the formula since my last attempt? Either way, I'll try to repro in a VM again, and if it doesn't happen, easy to close.

[liamdawson]

Okay, I successfully reproduced it in the virtual machine, here are more specific instructions:

• Create a virtual machine with default Virtualbox configuration for Ubuntu 18.10
• Attached Ubuntu 18.10 desktop media
• Ubuntu install with the following settings:
  
  
  
  • English (Australia) keyboard layout
  
  
  • Minimal install
  
  
  • Proprietary components included
  
  
  • LVM configuration
  
  
• After install, apt update and apt upgrade
• Install Linuxbrew
• apt install build-essential
• brew install hub

If there are still repro issues, I can upload the VM, but that will take quite a while.

[JuPlutonic]

Ok. I will renew and run Dockerfile, that actually using ubuntu/xenial ubuntu/cosmic contaner to test hub…

PS https://github.com/Homebrew/brew/issues/5561 is also bundle related with two possible ways to coupe with problems:
export HOMEBREW_FORCE_VENDOR_RUBY=1
or

export HOMEBREW_DEVELOPER=true; export HOMEBREW_RUBY_PATH=/home/linuxbrew/.linuxbrew/Cellar/ruby/2.6.0_1/bin/ruby

[JuPlutonic]

Freaking strange:
eerror.txt
My ubuntu/cosmic Dockerfile:
Dockerfile.txt

Run it with docker build command (100% :bangbang: reproducibility)

[iMichka]

I see also there errors in your file:

/bin/sh: 1: groff: not found
/bin/sh: 1: col: not found

These dependencies need to be added to the hub formula. We should try that out to see if it helps.

[JuPlutonic]

They actually present

if !OS.mac? && build.with?("docs")
    depends_on "bsdmainutils" => :build
    depends_on "groff" => :build
    depends_on "ruby" => :build
…

I don't know what to do with formula and with installed groff and colbsdmainutils. Nothing helped.
Variants I tried (see updated Dockerfile.txt):

• like in example above
• same, but without hashrocket => :build for groff and bsdmainutil
• tried to brew install groff and bsdmainutil before hub installation

Here's a related failed PR: https://github.com/Linuxbrew/homebrew-core/pull/10106

[iMichka]

I made some changes and built a bottle: #11450

I could not reproduce the bundler issues. But there were some hub updates lately, they maybe fixed it?

[JuPlutonic]

@iMichka, yes my ubuntu cosmic dockerfile used bottle:
🍺 /home/linuxbrew/.linuxbrew/Cellar/hub/2.8.4: 36 files, 8.1MB
No patches need to be applied

[sjackman]

Glad to hear that it's working!

[tobybellwood]

yup -working for me too on hub 2.8.4 :-)
