Thanks Till!

I don't know the code or expected workflow here, so I could be totally off
base, but it looks like _installSMBBackendIfNeeded() is trying to install
samba-client, which is a virtual package provided by smbclient. smbclient
depends on libsmbclient.

If you changed that to installing python3-smbc, you'd still get libsmbclient,
but I don't know if you're depending on something in smbclient that's not in
libsmbclient. If so, then I think you can just modify s-c-p's
PackageKit.InstallPackageName() method to accept multiple package names (or
add a new method that accepts more than one). Then you'd pass smbclient and
python3-smbclient to them.

But that may still hit the problem you're describing above.
