added a comment - I am basically installing jenkins on a VM created through proxmox. The current JENKINS_HOME configured on the UI is /va/lib/jenkins and as you suggested I tried export JENKINS_HOME=/.jenkins and moved everything from /var/lib/jenkins to /.jenkins directory in my VM and tried restarting the jenkins.
But i get following errors. Is there any other way to change JENKINS_HOME or why is it still trying to reach /var/lib/jenkins ?

But i get following errors. Is there any other way to change JENKINS_HOME or why is it still trying to reach /var/lib/jenkins ? Setting the JENKINS_HOME environment variable before running Jenkins should be enough. I just confirmed with my environment that I can use:
$ jdir=tmp$$ $ mkdir $jdir $ wget http://mirrors.jenkins.io/war/latest/jenkins.war $ JENKINS_HOME=`pwd`/$jdir java -jar jenkins.war --httpPort=9090
That starts a Jenkins server that is using the "jdir" that I defined.
You may also want to check that you are sizing the virtual machine adequately.
markewaite Thank you ! It seems changing the JAVA_HOME directory is some sort of solution even though I don't understand how that makes difference .
Setting the JAVA_HOME to /.jenkins and running by executing java - jar jenkins.war worked but I am rather trying to run the jenkins as the service.
The war file is placed in /usr/share/jenkins and systemctl start jenkins or /etc/init.d/jenkins start basically starts the jenkins. However, doing so I am not able to change the JENKINS_HOME to /.jenkins by using export JENKINS_HOME=/.jenkins

You don't need to change the JENKINS_HOME you use, just fix the contents of the default JENKINS_HOME directory
akafle the original submitter says that restarting the server resolved the issue. Since restarting the server does not resolve it for you, I assume you have a different issue at the root of the problem.
Can you duplicate the problem on another computer?
Can you duplicate the problem on the same computer when running Jenkins with a different JENKINS_HOME directory (see the wiki for JENKINS_HOME setting)?
