[Software] Update failed (to 25.10)

[checco]

When I try to upgrade my Kubuntu 25.04 to 25.10, I get a window that says "Upgrade failed with the following output:" but nothing is written (see screenshot). What can I do?

Don't use Discover.

Open Konsole. Type: sudo apt update && sudo apt full-upgrade to ensure that everything is 'up to date'. If any packages are reported as being held (phased), you won't/shouldn't attempt to upgrade to 25.10 yet.

If you aren't told any packages are being held, then type: sudo do-release-upgrade

Two packages appear to be upgradable, even though everything is up to date on discover. With sudo apt full-upgrade it tells me "Not yet updated due to staggering:
fwupd libfwupd3" How can I update them?

You can bypass the phasing hold on these two packages by running sudo apt -o APT::Get::Always-Include-Phased-Updates=true install fwupd libfwupd3 If the packages update without any issue (no ERRORS), you can run the sudo do-release-upgrade command.

Everything seems to have gone well, the packages are up to date. Tomorrow I'll try to launch the upgrade with the command 'sudo do-release-upgrade'. I'll let you know...for now, thanks.

I have experienced the same problem. The output of
sudo apt full-upgrade
shows me that
fwupd libfwupd3
are not upgrading yet due to phasing.
When I try
sudo apt -o APT::Get::Always-Include-Phased-Updates=true install fwupd libfwupd3
the output states
Error: Unable to locate package libfwupd3

It seems like "fwupd libfwupd3" have been phase-delayed for a very long time compared to other previous phasing delays.
Should I continue to wait on this? Or is this a problem with my system not performing correctly?

My nearly daily update regimen is:
sudo apt update
sudo apt list --upgradable
sudo apt full-upgrade
sudo apt autoremove


Here is the most recent operation and output of that regimen:

Am I doing something wrong?

Thanks, claydoh.
It's late and my eyes are dying on me, so I thought I'd write this before heading to bed.
Looking at your most recent link, I see there is a command do-release-upgrade -f DistUpgradeViewKDE that is being suggested.
I had tried a similar command earlier using the "-m" argument and the output claimed to not support that argument even though the man page claimed it was valid.
For now I will assume that the "-f" switch will work.
I hope to perform this task tomorrow.

Successful update to 25.10. Thanks to Snowhog for their contribution.

Yes, it seems Ubuntu removed the -m option at some point, which is what caused this bug in the applet, as it was coded to use it.

Which main page did you see the "m"? So we can get them to edit it if necessary.
