Investigations into the problem reveal that kcmshell5 appears to be waiting for qapt..

[21:30] <sick_rimmit> I am on 15.10 here right now [21:30] <clivejo> yes [21:31] <sick_rimmit> OK.. [21:31] <clivejo> I think it does same on 15.10 [21:31] <clivejo> can you try? [21:31] <sick_rimmit> Nope works for me [21:31] <clivejo> hummm [21:31] <clivejo> so whats changed! [21:31] <sick_rimmit> try calling it from the command line, see what output you get [21:32] <clivejo> nothing [21:32] <sick_rimmit> hmmm [21:32] <sick_rimmit> did your new builds of libqapt make it into Xenial, the one for muon ?

[21:40] <sick_rimmit> If you sit for a few seconds hands off machine does it continue output [21:41] <clivejo> yes [21:41] <sick_rimmit> strace is a Stack trace utility so it picks up mouse, kdb, everything really [21:41] <clivejo> just sits there doing that [21:41] <clivejo> until I close the window [21:41] <sick_rimmit> Ok so it is stuck in a loop doing something [21:42] <sick_rimmit> question is what ? [21:42] <sick_rimmit> so run it again without strace then ps uax to find its process id [21:42] <clivejo> was hoping you could answer that [21:42] <sick_rimmit> then lets try lsof [21:42] * sick_rimmit needs man pages [21:43] <sick_rimmit> ah yes [21:44] <sick_rimmit> lsof -p <pid> [21:44] <sick_rimmit> that will tell us what it is doing [21:45] <-- SilentGh1 (~SilentGho@unaffiliated/silentghost) has left this server (Ping timeout: 246 seconds).

[21:50] <sick_rimmit> So it's waiting on the qapt socket [21:50] <clivejo> what does that mean? [21:51] <sick_rimmit> it is an interprocess communication [21:51] --> superfly (quasselcor@ubuntu/member/superfly) has joined this channel. [21:51] <clivejo> ah [21:51] <sick_rimmit> kcm -> qapt [21:51] <sick_rimmit> so now it is qapt that is doing something and kcm is awaiting it [21:51] <sick_rimmit> so ps uax qapt [21:52] <sick_rimmit> and lsof again [21:52] <sick_rimmit> what is qapt doing ?
