CUPS does not work on Fedora 23

I recently updated from Fedora 19 to Fedora 23. Unfortunately, the CUPS server does not work and I can't print anything. I've spent several hours trying all the obvious and less obvious, but to no avail.

I suspect that if I had done a complete installation of fedora23 starting from scratch (instead of an update) it would be working. My question is: which files should I delete and then re-install to simulate a complete installation as far as CUPS is concerned?

  1. are there any error messages? Try gnome-logs or journalctl and reading files in /var/log/cups.
  2. Do you have stale config files? Search for files ending with .rpmnew or .rpmsave. rpmconf -a might be helpful here.
  3. do you have old (F19) packages installed? try dnf list installed | grep "fc19". They must be upgraded or removed. Having some F22 packages is okay though, because there was no mass rebuild scheduled between F22 and F23 release.
  4. can you open gnome-control-center ("Settings"), printer page? What does it look like? are there any printers configured?
  5. is your cups daemon running? What is not working? your description is a bit unprecise. What exactly works, what doesn't?

I was having trouble printing in Fedora 23 as well. The problem turned out to be SELinux. Try disabling SELinux with:

sudo setenforce 0

Then try printing again.
