Brew uninstall fails when upgrading

When updating git-credential-manager-core brew fails stating that the uninstall script is missing.

Hello -

It seems your local uninstall.sh script has gone missing. I removed my local copy of uninstall.sh and was able to retrieve it by running the following:

cd /usr/local/share/gcm-core &&
sudo curl \
-H 'Accept: application/vnd.github.v3.raw' \
-O \
-L https://api.github.com/repos/GitCredentialManager/git-credential-manager/contents/src/osx/Installer.Mac/uninstall.sh &&
sudo chmod +x uninstall.sh

After that, I believe brew upgrade git-credential-manager-core should work as expected.

I think there might be something else going on.

I don't have a /usr/local/share/ directory.
Here's the output for brew info git-credential-manager-core

Ah, I see now, your install location is different. Can you run the following and share your output?

ls -lsa /usr/local/bin | grep git-credential-manager-core

The default HOMEBREW_PREFIX is /usr/local on non-Apple silicon machines. However, it looks like for Apple Silicon it's been updated to /opt/homebrew. This is something we will need to account for on our end. I've created #574 to track.

Based on the output you shared above, it looks like GCM did at least update to the latest version. However, if you are experiencing issues with this installation, I would recommend running brew uninstall git-credential-manager-core then following the instructions in the README to install the latest package from the releases page. Note that you will likely have to right click on the package in your Downloads directory and select Open with -> Installer to do this as a result of some signing issues we are currently working through.

Closing in favor of #574.

This happens again on my Mac M2 machine and only started showing up recently, I cannot uninstall it though homebrew because the uninstall script is missing (if it's of any help I installed it using homebrew in the first place). Please let me know if there are any workarounds for this. Thanks!

EDIT: I did get past this by re-installing the cask but I still feel that it shouldn't be the go to option since the original issue has been closed for a while now.

Seems this issue has no active feedback yet, I will give a dirty work-around here for a quick fix. At least it didn't stop me from upgrading my "brew" packages after it.

Just write a simple script and put it on "/opt/homebrew/share/gcm-core/uninstall.sh" (or wherever it complains), make it executable. Mine was:

#!/bin/sh

exit 0

Then the upgrade will happily accept this script and no complains at all.

Same thing repeated again now and I had to re-install again. It would be great if the issue can be re-opened and looked at. Thanks!

[ldennington]

We’ve fixed this for new installs going forward. The workaround for those still affected is to uninstall using the following commands:

brew uninstall --cask --force git-credential-manager-core
/usr/local/share/gcm-core/uninstall.sh

Then re-install with the following commands:

brew update
brew install --cask git-credential-manager-core
