Update Jenkins from a war file

Question

I have a machine with Ubuntu 12.04 and have installed Jenkins ver. 1.424.6 using apt-get but there is a new version:

New version of Jenkins (1.447.2) is available for download (changelog).

If I press download, I get a Jenkins.war file... but how do I use that for upgrading my current installation? or is that not possible before the apt repositories get updated?

Answer 1

For this issue, you can overwrite the existing Jenkins.war file with the new one and then restart Jenkins.

This file is located in /usr/share/Jenkins.

If you don't find the path then navigate to Manage Jenkins -> System Information, it will display the path to the .war file under executable-war.
