Can’t sign in to Jenkins, GitHub API problem after plugin upgrades

[SethTisue]

@lrytz I upgraded some Jenkins plugins, including some that had security alerts, and now I can't authorize to Jenkins using GitHub; journalctl -u jenkins.service on jenkins-master shows:

this probably means that one of the upgrades caused some other plugin, probably the GitHub login plugin itself, to need to be upgraded? that's my best guess, anyway

do you have any experience with resolving this kind of thing? it looks to me like I could probably go in manually from the command line, disable login security entirely (as per https://www.jenkins.io/doc/book/security/access-control/disable/), and then try upgrading plugins through the web UI . but I'm a bit reluctant to mess with it any further, and perhaps break it even more, before you're back from your trip

as a test, I rebased scala/scala#11138 but no Jenkins job started, so I guess Scabot can't authenticate either. but that's not really an emergency since we have GitHub Actions doing PR validation

fyi @som-snytt

hub4j/github-api#2137

[lrytz]

Updated the github-api plugin in jenkins to the latest version, now it seems fine (scala/scala#11152)

[lrytz]

@SethTisue I went through https://scala-ci.typesafe.com/manage/pluginManager/installed and disabled a lot of them that I believe we don't need (you can sort the list by "Enabled").

If you have time, take a look around jenkins to see if everything works correctly. We can uninstall the disabled plugins at some point.

I also installed jre 21 on jenkins-master (from adoptium, /etc/apt/sources.list.d/adoptium.list), Jenkins runs on that now.

[lrytz]

I did a push -f to scala/scala#11150 and the build looks fine, commit status updates work.

SGTM — I'll keep an eye out for breakage
