"Configure sources" broken in Muon (Wily)

[Nikola Snele]

"Configure sources" is broken in Muon, Muon Updater and Muon Discover. It acts as "check for updates" button.

Status changed to 'Confirmed' because the bug affects multiple users.

Muon Discover's "Configure Software Sources" does nothing. I have not tested Muon.

I got newest Muon 5.4.0 from staging ppa.

Now when "configure sources" is clicked, window asking password pops up, but after typing password nothing happens. Software-properties-kde windows doesn't open.

Nikola,

I also noticed this when installing latest 5.4 on top of 15.04. I got the password pop up but nothing.

I can confirm this on 15.10. I ran "kdesudo software-properties-kde" from a terminal and it returned

No command 'software-properties-kde' found, did you mean:
 Command 'software-properties-kde' from package 'software-properties-kde' (universe)
software-properties-kde: command not found

So I copied the command suggested into the clipboard, pasted it after typing "kdesudo", and it worked which is odd since the commands look identical.

[Nikola Snele (n-schnelle)]

Fixed in 5.4.1 update.

[cmue81 (cmue81)]

There is a dependency missing: libkf5-bin needs to be installed, which did not get pulled in automatically during release upgrade on my system.

Issuing

sudo apt-get install libkf5su-bin

on the command line fixed the issue. In any case, the file
/usr/lib/x86_64-linux-gnu/libexec/kf5/kdesud

needs to be in place. Without libkf5su-bin just kdesu is installed in that location.

fix from #8 works for me, thank you
(Kubuntu 15.10 upgrade from 15.04 with kubuntu-ppa backports)
