Printer setup: system-config-printer fails with error

[c.monty]

Hi,
I have setup and configured my printer with Cups.
This worked w/o issues.

However, in a multi-user environment the default settings defined in Cups are not applied to non-admin users.

Therefore I tried to run system-config-printer as user with unprivileged permissions.
But this commend demands sudo and therefore I granted this permission.

Now system-config-printer reports this error:

Code Select Expand

manfred@pc5-desktop:~$ sudo system-config-printer
(system-config-printer.py:1823): dbind-WARNING **: 11:30:13.955: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

    NETWORK_PASSWORD = Secret.Schema.new("org.system.config.printer.store", Secret.SchemaFlags.NONE,
NameError: name 'Secret' is not defined


How can I fix this?
