[fixed] Error: lulu: uninstall script /Applications/LuLu.app/Contents/Resources/LuLu Uninstaller.app/Contents/MacOS/LuLu Uninstaller does not exist.

When I tried to upgrade LuLu the firewall with command brew upgrade lulu, I faced this error.

Error: lulu: uninstall script /Applications/LuLu.app/Contents/Resources/LuLu Uni
nstaller.app/Contents/MacOS/LuLu Uninstaller does not exist.

Then thought of trying to remove/uninstall lulu, then re-install it. So, I ran brew remove --cask lulu using homebrew package manager. But the same error occurred.

I thought maybe it did not upgrade as I did not use --cask in the first command. So, I re-ran it as brew upgrade --cask lulu but with no avail.

I searched on Google, and found un-related top result from Github issues about lulu and Big Sur , and a blog post about uninstalling LuLu from Mac OS. I thought that blog post would help, but I read it in vain. They was explaining how to remove lulu by moving the app into trash can.

After this long journey, I listed the help command of homebrew by brew --help. So, I figured out that I can force reinstall lulu with this command brew reinstall --cask --force lulu.

The command has --cask because lulu is a Mac-OS-native .dmg program, and --force which is used to install the app without checking for previously installed keg-only or non-migrated versions.

brew reinstall --cask --force lulu

And this command succeeded 👌 So I decided to share it with you. So, you can find the fix when you face the same issue. Thanks for reading, I hope this helps. Share if you care.
