I may have made a stupid mistake today. I say “may” because I at least saved my machine from being so messed up I would have had to reinstall it. What happened was that my Fedora-35 box became frozen up and would not budge under any circumstances that hit the power button.
This would have worked, but on reboot, flashing by quickly in red and white letters, was something about “CUPS”. Therefore I went into emergency maintenance mode and removed cups with “dnf erase cups”. Unfortunately, I failed to write down all the dependencies the went away with CUPS.
So, with my humble hat in my hand, I would like to ask if anyone knows what those dependencies are, or how to find out. I can’t even run system-config-printer and my job rests on printing at the end of a shift.
Any help, thanks in advance.

you should just be able to dnf install cups
edit … thanks @ilikelinux I should’ve thought about this more
sudo dnf rq --whatrequires cups
will get you what depends on it
…
if removing cups is the last thing you did you can get the list of things you removed by:
sudo dnf history list last info
or
sudo dnf history list --reverse
find the line with cups, and get the transaction number
sudo dnf history info <transaction number>
will also give you the the packages that were removed.
Then you can either install by hand
or
sudo dnf history undo <transaction number>
sorry about that

Thank you both very much! I followed the dependency trail, and ended up with a fully functioning CUPS system. I couldn’t have done it without you.
