I've installed native Jenkins 2.263.3 (latest stable Debian package ) and Java openJDK 8. The installation was successful.
However, once the installation came to the step "Customize Jenkins" and there were options to either choose Install suggested plugins or Select plugins to install. Both give the same result.
Jenkins UI will freeze for about a couple of seconds and then the error page shows as pictured below.
I tried restarting, re-install (same version) unfortunately, it doesn't change.
The error messages in /var/log/jenkins/jenkins.log
