Some times ago I installed qtikz on my system, but I don't remember if I did it via dpkg -i --force-architecture or directly from source (perhaps via checkinstall). In short, it is not working and I want to replace it with the qtikz 64 bit version of ubuntu precise (I am using ubuntu natty). So I downloaded the package and did:

sudo gdebi qtikz_0.10-1_amd64.deb

Which gives the error message:

dpkg: error processing qtikz_0.10-1_amd64.deb (--install):
 qtikz: 0.10-1 (Multi-Arch: no) is not co-installable with qtikz:i386 0.10-1 (Multi-Arch: no) which is currently installed
Errors were encountered while processing:

Then I tried to purge the old qtikz via aptitude: sudo aptitude purge qtikz, which gives me: No packages will be installed, upgraded, or removed. Similar result with dpkg -r qtikz.

aptitude search qtikz gives no results.

and via apt-get I get:

sudo apt-get purge qtikz
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Virtual packages like 'qtikz' can't be removed

locate qtikz results in


So any ideas, how to savely remove this package?

You need to specify the architecture when you remove i386 package. I.e. remove it by executing sudo dpkg -r qtikz:i386.

You could try using dpkg directly:

dpkg -P qtikz

Did it work?
