Using a wrong URL for the key.

Using 'remove' instead of 'add' for the apt-key command.

💡 Hint

Common Mistakes

Running Jenkins as root user which is unsafe.

Using wrong ExecStart command that does not launch Jenkins.

Not setting Restart to 'always' to keep Jenkins running.

The ExecStart runs Jenkins using Java and the war file. The User is 'jenkins' to run the service safely. Restart 'always' ensures Jenkins restarts if it crashes.
