--- Comment #8 from Alex Dănilă <nuor...@gmail.com> --- You are right. Sorry for all this noise, I used to remember to check this stuff before reporting bugs (I often use KDE from Unstable to get newer versions of software). $ dpkg -s okular | grep '^Version:' Version: 4:18.04.0-1 $ dpkg -s okular-extra-backends | grep '^Version:' Version: 4:17.12.2-2.2+b1 I installed a tested with a compatible okular-extra-backends from Experimental and it worked. -- You are receiving this mail because: You are watching all bug changes.
