Running brew upgrade or brew update results in some sort of git error
- Merge conflict
- Unfinished rebase
Use brew update-reset instead which I beleive downloads all the
updates/upgrades fresh
Use brew doctor to get tips on what can be done to improve your local brew setup
Use brew cleanup to remove old or unused files and directories
brew upgrade
Updating Homebrew...
fatal: It seems that there is already a rebase-apply directory, and
I wonder if you are in the middle of another rebase. If that is the
case, please try
git rebase (--continue | --abort | --skip)
If that is not the case, please
rm -fr ".git/rebase-apply"
and run me again. I am stopping in case you still have something
valuable there.
