Personally it was when I was trying to commit and I got stuck in an authentication loop of git asking for my username or email (even used --global) and it would not work or remember no matter what I tried (was recommended to reinstall mint, yeah no lmao not again).
Ended up installing the unofficial GUI and I'm MUCH happier but I tell ya if you bork something in Mint it's really hard to fix it if your not a CLI wizard.
Git GUI wise I can do all the basic stuff I need and if something breaks than I use the CLI because there's more documentation on it
