You should do it manually with command line
Command failed [128]: /usr/local/bin/git --git-dir=/repo/gitlab-satellites/xx/yyyy/.git --work-tree=/repo/gitlab-satellites/xx/yyyy checkout -b develop origin/develop
fatal: Unable to create '/repo/gitlab-satellites/xx/yyyy/.git/index.lock': File exists.
If no other git process is currently running, this probably means a
git process crashed in this repository earlier. Make sure no other git
process is running and remove the file manually to continue.
