Clicked "Upgrade"on Software Updater, yet button does nothing...

[Dennis N]

Now it shows 6 not upgraded, while before there were 9 not upgraded. I would run sudo apt autoremove just to clean things up a bit. Then try sudo do-release-upgrade once more.

....Maybe upgrade and packages are phased and isn't my turn yet?

[Dennis N]

I think (but don't know for sure) that one of the "held back" packages is preventing the upgrade. Once I had one "held back" package stopping an upgrade to the next version. I just removed it, upgraded, and reinstalled it again after the upgrade.

The only things in your list of 6 that to me look safe to remove are gcc-10-base and gcc-10-base:i386. Those are compiler related, and are not installed in my Ubuntu 22.04, so they are optional. If it were me, I would remove them, then run sudo apt full-upgrade and sudo do-release-upgrade again. The other 4 kept-back files are important system files - do not remove those.

Also, I would definitely be sure all my important files are backed up before doing the above suggestion or anything more. You might have to do a new install if all else fails.

I'm currently downloading newest version Ubuntu and plan to create bootable USB stick, just to be sure.
I will follow your instructions and see what happens.

It was "gcc-10-base:i386" that held whole thing back!

That must be a relief. You should now be able to upgrade to 24.04 either with Software Updater OR use do-release-upgrade in the terminal. Post again if it is successful. Upgrading in place saves time versus a new install with all the setup and personalizing you have to do afterwards.

Well, after much fighting and blundering(I won't even start to explain) I... I think my system is okay.(meh, I was wrong. Can't start LibreOffice... See https://ubuntuforums.org/showthread.php?t=2500350)


I'm so grateful for your patience.

(I will mark this thread as solved.)
