The system printing service doesn't seem to be available

[Simon Colston]

Fedora 31 Workstation

I installed Xfce to give it a try, didn't like it so I removed it.  Unfortunately, since then, when I go to Settings -> 
Devices -> Printers I get the message "Sorry! The system printing service doesn't seem to be available"

I did some googling and found out that CUPS is responsible for printing.  The timestamp on the file 
/etc/cups/subscriptions.conf.O is the time I installed Xfce and the timestamp on /etc/cups/subscriptions.conf.rpmsave is 
the time I removed Xfce.  So that's how I broke it, I guess.

I now only have 2 CUPS packages installed:
cups-libs.x86_64
cups-pk-helper.x86_64

Can I just install cups.x86_64 package or is there anything else I need to do to get printing working again?

How did you remove xfce?

If you used dnf, you can check the history to see what was removed.  You 
probably just need to install cups.

Thanks.  The dnf history looks really useful.  I was worried that other things were broken but I can use this to check 
the other stuff.  Installed cups and printing is back.  Thanks again.

maybe to compare

on an f31 gnome box:

rpm -qa | grep cups | sort

cups-2.2.12-3.fc31.x86_64
cups-client-2.2.12-3.fc31.x86_64
cups-filesystem-2.2.12-3.fc31.noarch
cups-filters-1.22.5-7.fc31.x86_64
cups-filters-libs-1.22.5-7.fc31.x86_64
cups-ipptool-2.2.12-3.fc31.x86_64
cups-libs-2.2.12-3.fc31.x86_64
cups-pk-helper-0.2.6-8.fc31.x86_64
gutenprint-cups-5.2.14-7.fc31.x86_64
python3-cups-1.9.74-4.fc31.x86_64

Yep, that's what I have now.  Thanks.
