Man what a fantastic guide! Thank you so much! I did have to go find an older version of the support-core plugin to get started, but this video had already shown the in's and out's of researching "Jenkins" already and after a couple of minutes was able to get it installed (along with a missing Metrics dependency plugin). Fantastic content!

[@Kruglord]

Boy, it's like you made this video just for me! Thank you so much, fantastic content

[@romans4471]

I really admire both Your knowledge and - probably even more - Your seldom attitude for deep pre update analysis.

[@nnutipa]

This is a pretty rare kind of video which teaches you how to think and analyze before things went wrong. Usual video just shows you how to do something without understanding.
P.S. containers are truly amazing in these "upgrade" scenarios.

Hi there,
After upgrading Jenkins when I am starting. It’s getting exited.

[@bronquel]

Am using a jenkins version of 2.19 and trying to upgrade and when trying to install the support core plugin it says the plugin is built for 2.2 or higher versions.. And jenkins will fail to load the plugin.. Please help

[@shankarraj3433]

Sir, Jenkins is not starting after upgrading to latest version.
How to resolve this problem?

[@camerontaylor2221]

support-core won't install with the version of Jenkins i have :(

[@PeterBriersPlus]

you can manually install an older version plugins.jenkins.io/support-core/#releases

[@mohammadarshaan3134]

Incomplete video. Your jenkins was running on jenkins:8080 then you created a container. Now how can you upgrade from this container to main jenkins server which is jenkins:8080 ?

[@JohnDoe_777]

I think the right way is get Jenkins out. It's like tamagotchi and takes too much time as a tool.
