Jenkins not able to fetch code from remote git

My jenkins build is suddenly not working now.The error is as follows:-

Fetching changes from the remote Git repository
 > git config remote.origin.url <url> # timeout=10
ERROR: Error fetching remote repo 'origin'

I am not able to figure out the root cause. I have checked the permission and ownership for jenkins home folder which is /var/lib/jenkins:- drwxrwxrwx 17 jenkins jenkins 4096 Jun 25 04:30 jenkins

Permission and ownership of .git folder inside workspace folder of jenkins is:- drwxrwxrwx 8 jenkins jenkins 4096 Jun 30 21:51 .git

Please guide me fix the problem.

I was seeing the same issue, but disk space and VM memory were not the problem. What fixed it for me was making the job re-clone on build:

1. Go to the job's "Configure" page
2. Under Source Code Management → Git → Additional Behaviors, add a behavior "Wipe out repository & force clone"
3. Save
4. Build

Experienced it when Jenkins VM was running out of disk space. Cleaned it up, don't see this problem anymore.

Try clearing out the workspace files and rebuilding.

In my case, fetching/downloading the remote code was quite slow and was aborted due to a timeout. So I increased the "Timeout (in minutes) for clone and fetch operations" to 20 minutes.

In my case, found that my infrastructure team member changed the ownership of the workspace. After changing folder ownership (in my case it jenkins:apache) its start working.

Thanks & Regards Jaiswar Vipin Kumar R.

I resolved this error by setting the User Account Control settings to "Never notify" and restarting the machine and reconnecting the node to Jenkins.

I fixed the issue cleaning every git directory stored on /var/lib/jenkins/caches:

sh-4.2$ rm -rf git*

we deleted the branches from gitlab, but the slaves weren't updated so we saw this error. We deleted the workspace and it looks ok
