I tried to install Krita via terminal sudo apt-get install krita and got an error message. Many packages depend on libqtcore4 (>= 4:4.8.0) which is not going to be installed.

I am using elementary OS freya 0.3.2.

Now the problem is that I can't install anything else, I get an error message. The packaging system is damaged.

So far I've tried sudo apt-get clean, sudo apt-get -f install and also removing and purging krita doesn't work.

When trying to install libqtcore4 e.g. after sudo apt-get autoremove -f, the following error pops up:

Sub-process /usr/bin/dpkg returned an error code (1) and there is a problem overwriting '/etc/xdg/Trolltech.conf'.

Does someone know a solution or can guide me in how to solve this problem?

  • krita is most likely for a older or newer version of Ubuntu. Try using the version for Ubuntu 14.04 – Suici Doga Apr 28 '16 at 12:56
  • Can you be more specific what that means to "try to use" an older version? How does it solve the broken package management? Thanks – jmjr Apr 28 '16 at 12:59
  • Trying to use a old version will try to install old dependencies. – Suici Doga Apr 28 '16 at 13:00
  • Try using the instructions @ krita.org/download/krita-desktop – Suici Doga Apr 28 '16 at 13:01

To install the latest and correct Krita on Ubuntu and derivatives (elementary OS) run the following commands

sudo add-apt-repository ppa:kubuntu-ppa/backports 
sudo apt-get update 
sudo apt-get install krita

This will add the PPA and install Krita.

  • Didn't work for me. Maybe because previous versions of Krita must be uninstalled? Unfortunately that is not possible, because the dpks is broken due to dependency issue of libqtcore4 package. – jmjr Apr 28 '16 at 14:28
  • The error was caused by a bug. Following comment #2 did do the trick. Now both dpkg and krita work. – jmjr Apr 28 '16 at 15:29
