brew cask upgrade fails when cache directory is missing

[jjeising]

General troubleshooting steps

• I have retried my command with --force and the issue is still present.
• I have checked the instructions for reporting bugs (or making requests) before opening the issue.
  • None of the templates was appropriate for my issue, or I’m not sure.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I understand that if I ignore these instructions, my issue may be closed without review.

Description of issue

brew cask upgrade fails downloading if ~Library/Caches/Homebrew/Cask is missing. After manually creating the Cask folder it works fine again.

brew doctor or --force did not create the folder. It should be created before starting to download packages.

Please post brew cask doctor

Please post brew cask doctor

Sorry, missed that. Fixed above.

[commitay]

Reproducible. Only occurs with upgrade, not fetch, install or reinstall.

[commitay]

Just out of curiosity, why was the cache directory missing?

[jjeising]

I didn't manually delete the directory. I tried reproducing this brew [cask] cleanup [-s] but the directory did not disappear. So I'm not sure. I think this has happened before, but as [re]install seems to restore it the issue might have been not immediately visible for me.

[saagarjha]

I'm seeing this issue as well. For some reason Travis CI seems to not have a cache folder for Homebrew Cask, which causes all brew upgrades to fail.
