Could not write config file

[xJom]

Hi!

Using Jenkins 2.46.1 LTS on an Ubuntu server, and a virtual Windows slave, we sometime get an error when initializing the git repo (from GitLab on the same Ubuntu server).

Originally, we thought it was an issue with the Git-plugin: https://issues.jenkins-ci.org/browse/JENKINS-41169

We have tried a lot of workarounds, like removing the entire workspace manually, adding delays in the start of the job, etc etc. (You can see it in the thread above.)

But nothing works as a solid solution. It is always coming back.

I am currently out of ideas on things to try, so please, if you can add some comment, that makes me dig in the right direction, it would be most welcome.

From the link:

Description
Sometimes, the git init-command fails because of the .git/config-file is non-writeable.
Logging into the slave, there seems to be nothing wrong with the permissions on the file.
When it is good, it just inits the repo.

Try to check the following:

- try to monitor the folder - who uses the folder (sysinternals may contain something useful)

- disable antivirus or similar software (if possible)

- print content of the folder before git checkout (is it pipeline job or freestyle?)

- check network connectivity (i.e. ping before 'git clone')

- try "git clone" as a part of 'batch script' step - it may give you more information

- disk space (your slave is virtual, maybe it shares a hardware disk with another virtual instances)
