I'm stuck in version 12.8 and get the message already the latest version (12.8+1)

Hello all,
I’m stuck in version 12.8 and I haven’t found anything about a similar case. If I enter
“sudo apt-get install xwiki-tomcat8-mysql”, I get the message “xwiki-tomcat8-mysql is already the latest version (12.8+1).”
What could be the cause?

(Ubuntu 20.04.5 LTS)


Did you run sudo apt-get update before sudo apt-get install?

Yes I did and just found and tried this post (Repository 'http://maven.xwiki.org stable/ Release' is no longer signed), but no change so far.

What exactly does sudo apt update tells you ? Could you paste the result for example ?

My apt speaks German and says:
OK:1 Index of /ubuntu focal InRelease
OK:2 Index of /ubuntu focal-updates InRelease
OK:3 Index of /ubuntu focal-backports InRelease
OK:4 Index of /ubuntu focal-security InRelease

Well, I don’t see any XWiki repository here. You seem to only have the standard Ubuntu repositories (might have been disabled during an Ubuntu upgrade, that’s a thing Ubuntu does with third party repositories during upgrade).

You might want to re-do Installation using Debian (.DEB) packages (XWiki.org).

I’ve reinstalled the repositories and it seems to be working.
I had thought I could display the installed repositories via
grep -rhE ^deb /etc/apt/sources.list*
and in this way xwiki repositories were listed.
Is there a possibility to perform the updates/upgrades version by version?
Unfortunately, the first attempt to update in one step was not successful.

When Ubuntu is upgraded, it comments the non-standard repositories declaration lines inside the files.

If you mean upgrade to 12.9, then 12.10, etc. you don’t need to do that no.

What problem did you have exactly ?

Now I’m stuck in Flavor upgrade. I get a timeout while trying to remove orphaned dependencies.

It’s like “Groundhog Day” every day, “XWiki Standard Flavor”-Upgrade.
How can I get out of the loop and move the upgrade forward?

Now the upgrade went through after all. Thanks for your help!
