Before opening your issue you must check our instructions for reporting bugs or making requests, as appropriate. Note the former has several links to help diagnose and fix common issues.
If none of those guides is appropriate, delete this template and explain your issue in detail.
Please note that if it is apparent you ignored the instructions for reporting issues, we may close the issue without review. Dealing with the same solved and documented problems leads to maintainer burnout and wasted hours. Those would be better spent improving Homebrew-Cask itself and fixing real bugs.
If the guides themselves were unclear, help us improve them! Open first an issue or pull request stating what you found confusing and only then your other issue.
Thank you for taking the time to make a correct report. The whole team appreciates it.
