Black screen on F42, rescue boot not working

If sudo dnf remove PackageKit-Qt5 lists this package only then remove it.

Then continue with ( hopefully w/o conflicts this time )

#this will probably install a lot of kde rpms.
sudo dnf upgrade --refresh   

#install the updated kwin
sudo dnf upgrade kwin\* --enable-repo=updates-testing

An error on oopen264 from Cisco) reopository - status code 404 for https://codecs GPG verification is enable but GPG signature is not available

I installed the kwin but don’t want to bring in the full update because it includes an updated kernel. It feels like I might just be making things worse with another kernel.

cisco, retry, this happens sometimes, or add --disable-repo=fedora-cisco-openh264

add -x kernel\* to exclude kernels from this update.

YEAH!!! I have video again!

THANK YOU for all your help!!!

Great.

You should be careful when upgrading to F43. I am aware of two problems that older systems that have been updated over the years will encounter in F43.

  1. authselect profile not defined
    No login screen after upgrade to f43 (Solved: authselect was never set up on a system upgraded through many versions)

  2. systemd has removed support for System V runlevel targets.
    After Fedora 43 dnf-upgrade default.target links to non-existent file - #10 by rocketraman

This must be fixed before attempting an upgrade to f43.

ah. thanks for the warning. I was hesitating because Xorg it going away in f43 - one of my applications seems to depend on it.

That worked for me. Thank you, thank you!
