Trying to upgrade my packages but I don't want to upgrade to 16.10. I ran sudo apt update then sudo apt upgrade to upgrade my packages but got this message in terminal

The following packages have unmet dependencies:
 libcjs0e : Conflicts: libcjs0 but 3.0.1-3build2 is to be installed
 python3-aptdaemon.pkcompat : Conflicts: packagekit
                              Conflicts: packagekit:i386

Should I purge/remove these packages and reinstall them? Thanks in advance for your help.

  • Just reinstall it.....and let us know – minigeek Oct 16 '16 at 16:44

I did this:

sudo apt-get purge python3-aptdaemon.pkcompat
sudo apt-get update
sudo apt-get upgrade

# after reboot
sudo do-release-upgrade

The package python3-apt-daemon.pkcompat had no dependencies remaining. The upgrade then proceeded normally.

  • My upgrade from 16.04 to 18.04 failed due to this problem. The above solution worked with apt replacing apt-get. Also, there was no need to do do-release-upgrade as apt upgrade did the necessary. – John Rose Oct 7 '18 at 8:36
  • I ran all these commands as well as the second answer from Favian. No show. Eventually, I ran each of the packages listed from ... apt list --upgradable one-by-one. I planned to update what I could/might and identify the fly-in-the-oinmment. Turns out everything succeeded and what ever the mismatch was was no longer. No idea what was in conflict -- Hope that work-around helps others. – will Nov 15 '18 at 6:04

This solved my problem in every situation :) run:

sudo apt-get -f autoremove
sudo apt-get update

then try again :

sudo apt-get upgrade

My upgrade from 14.04 via 16.04 to 18.04 failed for the same reason. Michael's solution worked when I used apt instead of apt-get.

sudo apt purge python3-aptdaemon.pkcompat
sudo apt update
sudo apt upgrade

"apt upgrade" failed partway through, but most of it completed when I ran a subsequent "apt purge" command.
