I have tried removing /root/.BuildServer/system/caches, but it does not work.

I suspect the agent does not have permission to run git fetch in the teamcity data.

TeamCity info:

• Version: 2024.12.2 (build 174504)
• OS: Ubuntu 24.04
• Git is available in /usr/bin.

Any solutions please ?

Thanks,

• Are you using server-side checkout or agent-side checkout? Also, please share the teamcity-vcs.log – slattman Commented Feb 16 at 21:15

Try fetching all heads but you'll need to enable it first firstteamcity.git.fetchAllHeads=true

It may also be worth checking if the remote repo is fine by using another client like tortoisegit?
