Issue with Google Music Manager Cask

[winkelsdorf]

Google Music Manager currently fails to install because it's unable to handle correct permissions requiring sudo for installing it's preference pane.

This should probably be escalated together with a similar problem with Parallels from #18638, as it looks like something broke the sudo handling, probably related to the new installation behavior from #13201 and #13966.

This single issue has low priority for me, but after this is the 2nd cask running into sudo issues with the new installation behavior, it's probably worth having a look into..

Bug description for this particular Cask

I removed all leftovers of previous installation and received this upon Installation via Cask:

 ~/Dropbox/Application Support/dotfiles/Update  brew cask install music-manager  
==> Downloading https://dl.google.com/dl/androidjumper/mac/2431116/musicmanager.dmg
Already downloaded: /Users/winkelsdorf/Library/Caches/Homebrew/music-manager-1.0.243.1116.dmg
==> Verifying checksum for Cask music-manager
==> Moving App 'MusicManager.app' to '/Applications/Music Manager.app'
Error: It seems the Preference Pane source is not there: '/opt/homebrew-cask/Caskroom/music-manager/1.0.243.1116/MusicManager.app/Contents/Helpers/MusicManager.prefPane'

Like with Parallels, sudoing solves this:

 ✘  ~/Dropbox/Application Support/dotfiles/Update  sudo brew cask install music-manager

Scenario 2: Uninstallation without sudo crashes, when previously installed with sudo

 ~/Dropbox/Application Support/dotfiles/Update  brew cask uninstall music-manager   
==> Removing App: '/Applications/Music Manager.app'

  Most likely, this means you have an outdated version of homebrew-cask. Please run:

      brew uninstall --force brew-cask; brew untap phinze/cask; brew update; brew cleanup; brew cask cleanup

  If this doesn’t fix the problem, please report this bug:

Two small notes:

1. parallels-desktop already had issues before (the linked issue is older than the recent changes), but that could very well be related to the cask itself (which had some problems that were already fixed).
2. The problem with this cask is a fun one. See how it says Error: It seems the Preference Pane source is not there: '/opt/homebrew-cask/Caskroom/music-manager/1.0.243.1116/MusicManager.app/Contents/Helpers/MusicManager.prefPane'? Well, it depends on what order we’re doing things (will have to check), If we moved the target from app before trying to get the target from prefpane, then it’s natural it can’t find it, because it would have already been moved. To fix that, the line would need to be prefpane "#{appdir}/MusicManager.app/Contents/Helpers/MusicManager.prefPane". That said, I don’t see a reason why we should be taking out the prefpane ourselves. Presumably the app will do it, so I’ll remove that line.

[vitorgalvao]

Should be fixed now. Closing.

[winkelsdorf]

Thanks for the clarification 👍

Agreed about the order of installation of the prefpane, verified MusicManager cask to be working correct now.
