Homebrew-cask: Bug report: installed casks not migrated after brew migration to /usr/local/Homebrew

[wojciech-milewski]

Description of issue

brew update moved installation location from /usr/local to /usr/local/Homebrew. Unfortunately, installed cask were not moved to /usr/local/Homebrew/Caskroom, so brew cask thinks that I have no installed cask.

For example, I have installed java at usr/local/Caskroom/java/1.8.0_102-b14, but brew cask info java says that it is not installed.

Output of brew cask info java --verbose

java: 1.8.0_102-b14

Previously installed casks are still achievable in the system, but I'm now sure if simple moving /usr/local/Caskroom/ content to /usr/local/Homebrew/Caskroom will be enough.

I noticed the same behavior just now. But I have a slightly different output for brew cask doctor

==> Homebrew-Cask Staging Location:
/usr/local/Homebrew/Caskroom (error: path does not exist)}

Because /usr/local/Homebrew/Caskroom does't exist on my machine brew cask list gives me:
Warning: nothing to list

[wojciech-milewski]

Yes, I had the same output for brew cask doctor, but actions described in pre bug report changed that.
brew cask list also gives me the same warning, because /usr/local/Homebrew/Caskroom is empty

[guycalledseven]

Yes same here. They are still in /usr/local/Caskroom/ and linked to my ~/Applications

brew cask list Warning: nothing to list

I did not have lates xcode-cmd when brew was upgrading cask. dunno if that was issue.

So do we wait for fix or do it manually?

mv /usr/local/Caskroom /usr/local/Homebrew
for f in ~/Applications/*.app; do oldloc="$(readlink "$f")"; [[ -e $oldloc ]] || ln -sf "/usr/local${oldloc#/opt/homebrew-cask}" "$f"; done

Or should I just remove brew and everything and reinstall to new locations since this is 2nd or 3rd move in last year? (was also in /opt/homebrew-cask/Caskroom) :)

edit: locations

[reitermarkus]

This should be fixed after https://github.com/Homebrew/brew/pull/1025 is merged.

Or should I just remove brew and everything and reinstall to new locations

@guycalledseven, this might be the best thing, since there is no automatic way to migrate the symlinks from the old installation behaviour.

[guycalledseven]

tnx @reitermarkus will do.
