On my side I got:

$ brew update
remote: Repository not found.
fatal: repository 'https://github.com/Homebrew/homebrew-dev-tools/' not found
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-dev-tools failed!

Hope this is useful!

[MikeMcQuaid]

@matteodisabatino @retokromer You both have tapped very old, long deprecated repositories. Please brew untap them and brew update will continue again.

[MikeMcQuaid]

Actually going to reopen this until we handle it a bit better in brew update.

[MikeMcQuaid]

Nothing to change here; brew update is completing in the case and updating everything as expected except the taps that no longer exist.

[SCdF]

Since no one has said it explicitly, as the error output doesn't contain the tap's name, you can either guess (!) or use brew tap-info --installed, and then match the failed URLs with the taps listed there, and _then_ pass that name to brew untap

[zhugejun]

UPDATE: found the solution here.

I am having another issue:

➜  ~ brew update                
remote: Repository not found.
fatal: repository 'https://github.com/Homebrew/homebrew-x11/' not found
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-x11 failed!

[iMichka]

You also need to untap the x11 repo.

[mikem]

I have slightly a slightly different error message for the homebrew-devel-only repo:

$ brew update
fatal: could not read Username for 'https://github.com': terminal prompts disabled
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-devel-only failed!

The "could not read Username" leads me to believe that maybe the homebrew-devel-only repo became private? Doesn't matter of course. I thought I'd leave this comment here for anyone else using "homebrew-devel-only" in their web searches.

Un-tapping homebrew-devel-only fixes the issue:

$ brew untap homebrew/devel-only
Untapping homebrew/devel-only...
Untapped (68 files, 36.7KB).
$ brew update
Already up-to-date.

@MikeMcQuaid

I am getting this error again, this time with taps that do not appear to be deprecated:

brew update
ssh: connect to host github.com port 22: Operation timed out
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I'd appreciate it if you could provide guidance.

@bartonfriedland This is unrelated to this issue. Please read the output you have pasted.
