Problem with 'cask upgrade' and virtualbox/virtualbox-extension-pack casks

[ev0rtex]

Description of issue

I'm reporting this issue as requested by @reitermarkus here.

While trying out the new implementation for brew cask upgrade at Homebrew/brew#3396 I ran into a problem with the virtualbox cask. On my system I have both virtualbox and virtualbox-extension-pack installed. When I run brew cask upgrade it appears that it uninstalls virtualbox-extension-pack and then fails to install the newer version because it assumes it is not an installed cask.

First I checked to see that they were outdated:

$ brew cask outdated
virtualbox (5.2.0-118431) != 5.2.2-119230
virtualbox-extension-pack (5.2.0-118431) != 5.2.2-119230

Next I tried the upgrade:

$ brew cask upgrade

virtualbox 5.2.2-119230, virtualbox-extension-pack 5.2.2-119230

Output of your command with --verbose --debug

I'm not sure of the easiest way to revert to the previous version to run this again with the --verbose and --debug flags but I suspect that won't be needed here. I'd be happy to figure it out if that is indeed helpful though.

[commitay]

This has been fixed with #40615. It won't occur with future virtualbox / virtualbox-extension-pack upgrades.

Thanks for reporting this nonetheless.
