Just FYI,
I had unattended-upgrades updating my Jenkins install on Debian automatically from
pkg.jenkins-ci.org. This had been running fine for a long time, however I noticed the upgrades were stuck on version 2.8 and didn't continue. Apparently the "origin" parameter of the package has changed from "
jenkins-ci.org" to "
jenkins.io". So, when you are using allowed-origins to automatically update jenkins, you might have to edit / add that value for the Jenkins repository.
Kind regards,
Pieter-Jan
