I tried uninstalling it from YAST2 software manager but I found that it is marked as uninstalled.
Then I tried from command line
sudo zypper rm anki
and got this
Loading repository data...
Reading installed packages...
'anki' not found in package names. Trying capabilities.
No provider of 'anki' found.
Resolving package dependencies...
Nothing to do.
I installed anki on my system using the instructions on their homepage which is: downloading the compiled package then running:
$ tar xjf Downloads/anki-2.0.45-amd64.tar.bz2
$ cd anki-2.0.45
$ sudo make install
And I'm using a custom made SUSE Linux based on openSUSE Leap 42.1 JeOS
