I have it all fixed now and uploaded as system-config-printer
1.5.7+20160212-0ubuntu2. Here python3-smbc is demoted to Suggests: and
the option for setting up a "Windows Printer via SAMBA" is already
available in the list of available devices if smbclient (contains the
"smb" CUPS backend) is not installed.
If the user chooses the "Windows Printer via SAMBA" and clicks either
the "Browse" or the "Verify" button, python3-smbc gets installed, as it
is used by these functions.
If the user sets up a printer with a "smb://..." URI, the smbclient
package gets installed as the "smb" CUPS backend is needed to use this
To make the installation of the packages exit only when the packages are
actually installed, I succeeded to solve after some Googling. The
InstallPackageNames() D-Bus method of PackageKit has a parameter to
select which stages of the installation process should be displayed or
not and the method exits after the last displayed stage, and lets the
installation go on in the background if there are more stages. Now I let
the last stage get displayed and everything works as intended.
