I tried to update one of my Jenkins instances to 2.107.1 and on restart it will not come up.
The puzzling thing is this Jenkins instance is the same as another yet that one updated just fine.
I did update all the plugins prior to attempting to upgrade.
I only see this in the error log:
INFO: Listed all plugins
Mar 30, 2018 8:53:35 AM org.jenkinsci.plugins.scriptler.ScriptlerPluginImpl synchronizeConfig
INFO: initialize scriptler
I don't use Scriptler at all, it's just a dependency but again, same thing on another server and it upgrades just fine.
I then tried disabling scripter and then it just stops after this and never continues:

I have successfully reverted back to the previous version.
