Troubleshooting

Git hasn't been working for me at all at any point

Uninstall Git and Git LFS from your system. Also delete C:\Program Files\Git (or where ever you chose to install it). Then restart your system and then reinstall.

I entered the wrong credentials for git and now git automatically fails

You can edit your saved credentials by opening the Credential Manager (search for it in Windows Search or in the Control Panel > User Accounts > Credential Manager). Then open Windows Credentials and under the Generic Credentials, expand the dropdowns for the credentials you want to edit, and then click the Edit link to change it.

There are no remote branches besides main/promoted and my own local ones

You'll need to set up tracking remote branches once. Enter this into Git Bash in your pb folder.

git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"
git fetch origin

My problem wasn't here

Ask about it in the #tech-support channel on the Discord.

PBSync cannot find my Git installation for PB

If you have a custom Git installation, or if you have multiple versions of Git installed and don't want the version PB requires to be the default, you can set up custom paths for both Git and Git LFS in .ue4v-user:

[paths]
git = C:\Program Files\Git\cmd\git.exe
git-lfs = C:\Program Files\Git LFS\bin\git-lfs.exe
