export JENKINS_HOME=/data

Answer 1

So your JENKINS_HOME environment variable is not correctly set.
For Ubuntu, you have to update this profile file ~/.profile and add this line export JENKINS_HOME=/data.
Next, you have to logout/login to take into account this change.
If Jenkins is running with a system account, open a session with this account and launch this command: . ~/.profile
