Launching system-config-printer from an administrator user (not root), authentication seems broken when I try to rename a printer. system-config-printer asks for my password two times, then asks for the root password in a gtk dialog, and finally give me a CUPS error dialog. It leaves the old named printer as is, a creates a new printer with the new name, but with incorrect properties (the print queue is file:///dev/null).

I can't reproduce that here. Please run 'system-config-printer --debug' and show the full output you get when you see this problem.

OK, I think the problem here is that cups-pk-helper is not allowing the location string even though it's valid UTF-8. PolicyKit call to PrinterSetLocation did not work: dbus.String(u'"B\xe2timent long - 1er \xe9tage - Caf\xe9t\xe9ria" is not a valid location.')
Maybe my problem is the same. I did activities->sundry->print settings a black window came up with the line "system policy prevents to change the firewall configuration" [I guess the programmer's native language is not English.] Then when I give my password it says "sorry that did not work" Then a second instance of same in regard to changing the printer configuration. In my case I'm trying to add a printer to a newly installed F19 system.
Jim: I don't think the problem you are seeing is the same. Please file a separate bug report, and follow the instructions in comment #2.
Thanks. But I've found Gnome to be broken in so many places I just gave up on it and installed from the Xfce spin. It doesn't seem to have this authentication problem in configuring printers.
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
