It seems that there are still some issues here. I did as you suggested and updated libkipi-4.8.3 to 4.9.2, but this removed digikam, showfoto, and a couple of other things. I thought I would just re-install them, but now I can't!
Get this message when I try to install digikam (after updating libkipi-4.8.3 to 4.9.2 and getting gwenview working):
Depends: libkipi.so.8 but it is not installable
Anyone any ideas?
