[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.
