FOREMOST, IT'S A WARNING TO ALL USERS WHICH HAVE MAYBE THE SAME ISSUE. HANDS AWAY FROM MANUALLY INSTALLING OF CUPS ON UBUNTU!!!
I thought that my problem could only have been caused by an error in the cups system. Foremost I did this from comment 3: https://askubuntu.com/questions/1286047/how-to-upgrade-cups-and-cups-filters-in-ubuntu-20-04-to-the-latest-versions-that cd ~/home/newcomer01/Downloads tar –zxvf cups-2.3.3-source.tar.gz cd /cups-2.3.3 ./configure make sudo make install It compiles/installs a lot of stuff, nobody knows if all these files and services really needed. After that, the complete cups System was broken and the command "sudo systemctl start cups" was never be able to start any cups-processes, due to lot file and dependencies issues from the box. Lot of hours I've spent to fix the errors, but without success. Now I searched again and found this: https://answers.launchpad.net/ubuntu/+question/817322 Then I do: sudo apt-get purge cups && sudo apt-get autoremove sudo apt-get update && sudo apt-get install cups sudo snap install cups Then I visited: https://github.com/OpenPrinting/cups-snap And followed all suggested steps, see attached "cups_snap.txt" file. My Printer works again (with the snap-package of cups) but the Problem with the gnome-control-center (https://ibb.co/Sfxz7nY) exists further, maybe someone is able to find and fix this issue together with me. Otherwise, I need to wait, maybe future updates of component software or something will fix it again. I really don't know how I should search/find/fix this issue - don't know it's cause, sorry. ** Attachment added: "cups_snap.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/2083530/+attachment/5824914/+files/cups_snap.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/2083530 Title: gnome-control-center not able to add printer or make settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/2083530/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
