I see that your original post is after ‘mozilla-openh264’ which wasn’t one of my dependancies but also seems to be failing. Try this:
wget -P /tmp http://ciscobinary.openh264.org/openh264-2.4.1-2.fc41.x86_64.rpm http://ciscobinary.openh264.org/mozilla-openh264-2.4.1-2.fc41.x86_64.rpm
dnf install /tmp/openh264-2.4.1-2.fc41.x86_64.rpm /tmp/mozilla-openh264-2.4.1-2.fc41.x86_64.rpm
and then try running your update.
@doineann I was thinking just as a temporary fix, however I’m installing this stuff in containers I’m probably going to remove quite soon so it’s a bit different.
dnf info openh264 lists the repository as @commandline so I imagine dnf would have some trouble finding updates but I could be wrong.
Looks like it is currently being fixed
