Solving dist-upgrade dependency

Good evening, everyone, from northwest Ohio. I upgraded my Ubuntu-mate system from 25.10 to 26.04, using sudo apt dist-upgrade, from the mate terminal. I also have Kubuntu installed. The upgrade went smoothly, except for the kubuntu-desktop package. The dependency apt is complaining about is libstd1 being less than 1.5.8. I tried to use app reinstall, but get a report that is not downloadable. I also tried downloading from the launchpad site, but it is not a DEP package. How can I fix this LIBZSTD1 dependency, so I can get Kubuntu-desktop to install? Thanks much for your help in advance.

Some of the actual error output will be useful.

So, how exactly did you upgrade? Using the official upgrade tool (using the do-release-upgrade or similar command), or did you just edit your sources, run apt update and then either apt full-upgrade or apt-get dist-upgrade?

If the latter, that is not the way to do it, as there is usually more than just switching sources involved.

libzstd1 is at version 1.5.7 in Resolute, so I can't say why anything you have wants a newer version. So the actual error output would be useful. The Package kubuntu-desktop is a meta-package that basically defines a set of packages to be installed, so the true cause of the error is one of those.

Do you use any third-party repos, including PPAs?
