I already have Jenkins 2.150.1 installed, so I tried downloading the new version (2.150.3). However, after installing and restarting, it's still loading the previous version.
In the notifications, it says that version 2.150.3 is available. When I click and download Jenkins.war version 2.150.3 and install it the terminal using
java -jar jenkins.war. As expected, it installs the new version, and then I close the terminal.
When I restart the PC or Jenkins, it's loading the old version of Jenkins again.
How do I update Jenkins without deleting the current jobs and having to re-install any plugins?
