mediathek install failing

[falkorichter]

I did the usual cleanup and upgrade but mediathek does not install As I understand https://github.com/caskroom/homebrew-cask/blob/master/Casks/mediathekview.rb is still an old recipe. Should they still work?

➜  ~ git:(master) ✗ brew cask install mediathekview

this is the output of the clean command, very weird it tells me there is no brew-cask installed

➜  ~ git:(master) ✗ brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup

my brew list

so I unlinked cask and reinstalled:

➜  ~ git:(master) ✗ brew unlink brew-cask

Error: No available formula for brew-cask 

then the install worked:

➜  ~ git:(master) ✗ 
brew cask install mediathekview

my taps:

➜  ~ git:(master) ✗ brew tap
caskroom/cask
caskroom/versions
homebrew/versions

I suspect the versions to be outdated so I removed them:

➜  ~ git:(master) ✗ brew tap      
caskroom/cask
homebrew/versions

What’s the issue, then? It seems like the installation ended up working.

This is a known problem (#6179, #6539); unfortunately, there is little we can do. I defer the explanation to https://github.com/caskroom/homebrew-cask/issues/6539#issuecomment-58272780:

This is some sort of problem in the Homebrew codebase, which occurs when you run brew upgrade brew-cask.

The cause is unknown, and there is no sharing of code or personnel between our two projects. If your command starts with brew but not brew cask, then none of our code gets executed, and there is nothing that we can change here to make it work.

That doesn't mean we aren't sympathetic; quite the contrary. At some point we added brew cleanup && brew cask cleanup to the lengthy recommended command because it helped some users with similar issues.

The usual solution to this glitch is some degree of un-installing and re-installing Homebrew-cask, as in https://github.com/caskroom/homebrew-cask/issues/6179#issuecomment-56262117 .
