Whenever I want to update my packages I receive the following error message: "An error occurred while applying changes:" This problem exists only since a few days, before that I had no problems. When I click on "Details" no further details on the error message are shown Reproducible: Always Steps to Reproduce: 1.open Muon Update Manager 2.Check for Updates 3.Install --> BOOM FAIL
I'm using Ubuntu 14.04.3 LTS
maybe the following info is helpful too. when I run muon-updater from the console I observe the following error message: found error while replying QDBusError("org.freedesktop.DBus.Error.InvalidArgs", "")

I have 2 Kubuntu machines, up to date version 15.10. Both has same error (see attached picture) every time they are updated with Muon, or if I try to install or remove packages with Muon Discover. The error message is always the same. Muon ver: 5.4.2 I run upgrade also from treminal. Listing of the terminal printout is attached.
I find out that: both of my machines where clean install, ie. in the installation process two disk partition were made. First one only 243MB (the one where system files are stored). During system update process Muon leaves old system files on the disk. After few system updates system disk becomes to full and updates are no longer possible. I used command: sudo apt-get autoremove -f to get more disk space. In my opinion, Muon should remove old, unnecessary, files from disk during update process.
Looks like a packaging issue in the distribution.
