We have a cron job which runs on the server and looks like this:

```auto
#!/bin/bash
UPDATE_LIST=$( ssh -l admin -p 8022 localhost list-plugins | grep -e ')$' | awk '{ print $1 }' )

if [-n "$UPDATE_LIST"]; then
    logger "The following Jenkins plugins will be updated: $UPDATE_LIST"
    ssh -l admin -p 8022 localhost install-plugin ${UPDATE_LIST}
    # Jenkins doens't seem to restart properly after an update
    # Restart it twice to attempt to clear the issues
    ssh -l admin -p 8022 localhost safe-restart
    sleep 1m
    ssh -l admin -p 8022 localhost safe-restart
fi

```

We’ve recently included the sleep and the second “safe-restart” because after this script runs every night, we get spurious error messages about Java trust anchors and issues with git like this:

```auto
05:02:00 ERROR: Error cloning remote repo 'origin'
05:02:00 hudson.plugins.git.GitException: Could not init /var/lib/jenkins/workspace/amphora-el9
05:02:00 at PluginClassLoader for git-client//org.jenkinsci.plugins.gitclient.CliGitAPIImpl$5.execute(CliGitAPIImpl.java:1085)

05:02:00 at hudson.scm.SCM.checkout(SCM.java:540)

```

It’s like the environment is trashed in some way and various things (including “git”) cannot be found:

```auto
05:02:00 Caused by: java.io.IOException: Cannot run program "git" (in directory "/var/lib/jenkins/workspace/amphora-el9"): error=2, No such file or directory

```

We can work around this by issuing:

```auto
systemctl restart jenkins.service 

```

However we dont want to “automate” this incase a job is running.  
Any advice would be appreciated.
