• I made doubly sure this is not a checksum does not match error.

Description of issue

Possible duplicate of #71595.

When I run many brew cask commands, they fail with Error: Cask 'kdiff3' is unavailable: No Cask with this name exists.

$ brew cask upgrade
Error: Cask 'kdiff3' is unavailable: No Cask with this name exists.
$ brew cask upgrade --force
Error: Cask 'kdiff3' is unavailable: No Cask with this name exists.
$ brew cask uninstall kdiff3
Error: Cask 'kdiff3' is unavailable: No Cask with this name exists.
$ brew cask uninstall --force kdiff3
Error: Cask 'kdiff3' is unavailable: No Cask with this name exists.

Command that failed

Output of command with --force --verbose --debug

$ brew cask upgrade --force --verbose --debug
Error: Cask 'kdiff3' is unavailable: No Cask with this name exists.

Additional Notes

This problem existed before I ran brew tap homebrew/homebrew-cask-versions; I then ran that command as suggested in #71595. It didn't help.

This is probably related to #67726; I'm sorry to see kdiff3 go, but it's understandable. This is perhaps the first time I've run brew update and brew cask upgrade since then. At this point, I'd be fine with just removing kdiff3, but homebrew doesn't seem able to follow that command right now.

[wackywendell]

Note: I ran rm -rf "$(brew --prefix)/Caskroom/kdiff3, and that worked.

For me, this isn't a problem, but it might be good to fix this for others.

[wren]

Confirmed that rm -rf "$(brew --prefix)/Caskroom/kdiff3" fixes for me, but without this many cask commands fail. Also, brew bundle commands lose all casks (I'm assuming the casks are left out because the cask command failed to return the installed casks to brew bundle).

This seems like a wide-ranging bug, since anyone with a cask installed that is removed from homebrew will experience it.

We’re aware this is suboptimal. You may wish to open a new issue discussing the generic problem:

But otherwise this issue in particular has nothing more to act on.
