Does missing Config.xml file in the domain indicate improper installation of jenkins?

[Ruqsar Shalu]

We have Jenkins installed in few of our internal domains, but when we try to create jobs we get errors (attached).

How do we validate if Jenkins has been installed in a correct way?

Also, I do not find the config.xml file in the Jenkins folder, does this indicate improper installation?

Hii

might be faulty installation.

1. take jenkins job backup (if any jobs) : /var/lib/jenkins/jobs

2. purge Jenkins: apt-get purge --auto-remove jenkins

3. Install from Scratch:  https://www.digitalocean.com/community/tutorials/how-to-install-jenkins-on-ubuntu-16-04

good luck!
