PC-TECH baselayout was a package rolled out last night to address a couple wrinkles. maybe it conflicts with ISO?
I wish I could help but it's brand new and I am going to defer to a DEV or Maintainer on this one.

From a clean install this failure can happen. There is a workaround though, when the update fails just re-run it before you reboot. The second update should succeed.

What day you have today in USA ?
Is today Friday in USA ?
I wonder there was "update actualization" window popping up today (in Germany ?).

    Applied updates no issues to report (Budgie)
    Keep up the great work!

    Finally got the courage to update my main work/game PC. No issues or errors at all. Plasma version. Will start updating the rest and let my friends and family know to go ahead and update. Will report how that goes. Some are a couple updates behind, others are up to date. All are Plasma.

      zmaint Please share whether any hiccups happens... I am terrified of updating my work computer.

        lf-araujo I had to head out for work (I travel lightly). Plan on doing updates when I get back this afternoon. Will def post here and let you know how it goes.

        This is the PC for my entertainment center, Plasma, all AMD. I hadn't updated it for about 3-4 weeks due to not enough sun (live offgrid). Just tried to update.

        Used this and it is now updating again:

        /usr/bin/wget https://packages.getsol.us/unstable/e/eopkg4-bin/eopkg4-bin-4.0.0-17-1-x86_64.eopkg
        /usr/bin/unzip eopkg4-bin-4.0.0-17-1-x86_64.eopkg
        /usr/bin/tar xf install.tar.xz
        sudo ./usr/bin/eopkg4-bin up

        Had to also use sudo eopkg update-repo --force to update my pickle.

        Rebooted, seems to be working fine.

        Did the wife's laptop, same as mine, had not been updated in a month. 0 issues.

        We just made some additional changes that will make it so that PCs that were behind on updates should now be able to update reliably. Note that this will not appear as a new update for anyone who has already updated.

        This issue should now be completely resolved.

          ReillyBrogan Awesome. I'm updating my friends and family network tomorrow remotely, just in case... Will post if I run into any issues. Very much appreciate everyone's help in getting a solution out so quickly!

            ReillyBrogan Just finished updating 3 PC and 2 laptops, only have 1 friends PC left to do, and have had 0 issues. Thank you again for all the help, you guys do fantastic work.

            Hi everyone! Sorry but yesterday I have faced the same problem, and being unable to recovery, used to do the eopkg trick and I was able to update, but I am still unable to get it boot.

            When I run the clr-boot update I get the "No kernels detected on system to update".

            And still the installed package manager gets the following error :

            Traceback (most recent call last):
            File "/usr/bin/eopkg", line 19, in <module>
            import pisi
            ImportError: No module named pisi

              jacojacker I have managed to fix it by running the eopkg check oneliner, but I am still unable to reach to the login screen.
