I made a big mistake, and updated Ubuntu from 16.04 (java 8, tomcat8) to 18.04 (java 11, tomcat8) at the same time as upgrading the wiki from 11.2 to 11.6.1. I now have the following symptoms:
No Distribution Wizard, even after following the instructions here: https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/DistributionWizard#HTroubleshooting
No Navigation, either in the left-hand Navigation Panel or in the Breadcrumb drop-downs. The Navigation Panel is just blank, the dropdowns say
Broken page titles and links in the admin page, which say things like:
administration.sectionTitle.global – the weird thing about this is if I change the theme back and forth a couple of times, the page titles start showing up.
No CKEditor, just some funky older-looking editor on the pages.
No panels, especially anything needing the Document Tree Macro say:
Unknown macro: documentTree. The "documentTree" macro is not in the list of registered macros. Verify the spelling or contact your administrator.
I uninstalled Glowroot (it was throwing errors in
catalina.out) and I was slowly able to upgrade all of the old Extensions, so those are all as modern as they can be. If it is helpful I can provide
catalina.out or other logs files. It is hard for me to tell what is useful errors in that log.
I am sure there are more symptoms, but this is just the main list. I am at my wits end here, any help would be appreciated. Even if it is “backup the wiki and reinstall on Ubuntu 16.04” (which is on my roadmap of things to try next). I just need some next-steps guidance. Thanks in advance!
Quick edit: I already diff / merged the old and new configuration files, so those are all as modern as possible as far as I can tell.
