Yeah I kind of realised that the instructions assumed I had already upgraded, will try to keep track of new updates better in the future. So for sake of completion here’s how I solved it in the end:
Ran into conflicts: file /usr/lib64/libopenh264.so.2.3.1 conflicts between attempted installs of openh264-2.3.1-2.fc38.x86_64 and noopenh264-0.1.0~openh264_2.3.1-2.fc38.x86_64
Solved it with exclusion: sudo dnf -v system-upgrade download --releasever=38 --allowerasing --exclude=openh264.x86_64
Fonts and glitches are gone, got some broken deps instead. So if anyone got a suggestion for that instead let me know. Otherwise I’ll do as it suggest –best --allowerasing’ and see what else breaks:
