I recently installed Kubuntu 14.04 and I installed available updates. Then, I got a black screen with mouse pointer visible. I lost my desktop. However I got to terminal with Ctrl+Alt+F1
. Then I ran sudo apt-get install kubuntu-desktop
. It gave me my desktop back.
Unfortunately, I found that some applications were broken and missing such as muon, dolphin, kontact, ktp-contactlist, etc. I tried several tips about package and apt commands. Nothing worked. sudo apt-get update
and sudo apt-get upgrade
did not solve the problem. Nothing was upgraded.
I could successfully installed dolphin by running sudo apt-get install dolphin
. But I failed with muon
and kontact
. The below is what I tried for muon
.
sithu@sithu-kubuntu:~$ sudo apt-get install muon

I tried to install libmuonprivate2
, but it depends on software-properties-kde

I also tried to locate and re-install broken packages using Synaptic Package Manager, but no luck. Applying the changes gave me this dialog:
Could not apply changes!
Fix broken packages first.
"Fix broken packages" gave me this dialog:
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
Any help would be highly appreciated.

.python3-software-properties
but it is not easy to say what. Could you try to purge it and then installmuon
?apt-get purge python3-software-properties
andapt-get install muon
reinstalled muon successfully. It also solved another problem ofkdeplasma-addons
re-installation. If you add an answer for this, I will accept it. It will be great if you could add the reason ofpurge
. However, it is difficult to fix the packages which have a lot dependencies such askontact
. Please check what I did withkontact
. Is there any better way to solve this.
