Unmet dependency problem caused by kipi-plugins I think.

It is going to happen with a repository that is constantly updating some software while other software packages do not.

**justlinux** · Aug 30, 2016, 10:32 AM

In this instance, there were some downgrades on the Python settings. Don't really remember the exact package names but after upgrading it I did another update and then another upgrade or dist-upgrade which downgraded about 3 packages and updated gwenview.

I don't recall seeing this before swithing to KDE Neon, though that might have been simply because I did not pay attention well enough.

Yes, that forced downgrade is part of the solution.

**Snowhog** · Aug 30, 2016, 11:59 AM

Posted yesterday on KDE neon FB page:

KDE Connect 1.0 added to KDE neon User Edition, plus kipi-plugins makes a return with support in Gwenview & Digikam.
(You may need to upgrade twice to get the new kipi-plugins, this is to remove the old pin file which kept it on kde4 kipi-plugins before we got the new Digikam.)

What will I lose or break if I force the upgrade? What does those packages do?

tahaan@komputer:~/Downloads$

How do I know whether it was worth it. In other words - what bugs were fixed in the latest update of gwenview?

Last night when I tried to mount/unmount an external drive, it failed to unmount, saying that there were open files. fuser did not show any processes, but when I did a ps I saw a couple of defunct gwenview processes. I did a

Code:

killall gwenview

after which the external drive could be unmounted... So I would like to see if any bugs appear to be related to this symptom...

**justlinux** · Sep 02, 2016, 08:44 AM

After the downgrade, did you do another update and upgrade and then upgrade gwenview? Something I have noticed on Neon that helps after upgrading sometimes, log out and then log back in to let the changes take full effect.

**Tahaan** · Sep 02, 2016, 09:39 AM

First I did update/upgrade the normal way, which is when I noticed that gwenview was being held back.

Then I did the upgrade and specified the gwenview package, which performed the downgrade.

After that there was no new updates for 2 days. AFAIK the two "software properties" packages are still downgraded (and presumably will stay that way?)

**acheron** · Sep 02, 2016, 09:50 AM

The downgrade of those packages to the stable versions is fine in this case, as it's needed to catch a Xenial stable release update that the higher neon version would otherwise have blocked.
