Upgrading cask: It seems there is already an App Suite at ...

[SebDominguez]

Each time I try to update KiCad using homebrew I have this error:

➜  ~ brew upgrade kicad

Error: kicad: It seems there is already an App Suite at '/usr/local/Caskroom/kicad/6.0.9-0/KiCad'.

My workaround was to uninstall completely the older version and then reinstalling KiCad but I wonder if there is a proper way to upgrade this cask

➜  ~ brew update && brew update && brew doctor && brew cu

Hey @SebDominguez

This is issue with the cask itself, doesn't really have anything to do with this repo. Even the command itself isn't the one provided here. Not sure if running brew cu for this makes a difference, but it's probably a problem with the cask itself. So not sure if there is any solution.
