SUMMARY When opening *.cbr files without unrar installed Okular returns a generic, unhelpful error message. STEPS TO REPRODUCE 1. Open a cbr file when the unrar package is not installed on the system OBSERVED RESULT Okular makes a loud 'DING!' and provides a generic error: Error - Okular Could not open file:///path/to/file.cbr EXPECTED RESULT Expected a helpful error message such as: "This file type requires the unrar package. Please install unrar to view comic books files." SOFTWARE/OS VERSIONS Linux/KDE Plasma: Linux 5.4.22-1-MANJARO KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.66.0 Qt Version: 5.14.1 ADDITIONAL INFORMATION When I tried to open a cbr file I got this error, and searching led me to a thread with someone who previously had the same issue and a question of "Do you have unrar installed?" - which I tried and it resolved the issue. A simple change to the error message would help immensly and be more user-friendly. Even better would be a button to "Download" that could automatically search for unrar in the package manager, though I realize that could be much more difficult if not impossible.
That's exactly what we say https://i.imgur.com/nK3IhdM.png I'm confused as to why you wouldn't be getting that message, anything in particular from your setup that you think may cause you to get a different error message?
I am using the regular stable version of Manjaro KDE. To confirm it isn't my setup I tried the same thing on another PC that has had almost no use since the Manjaro install, and it has the same result. Maybe something weird that Manjaro did on packaging? https://i.imgur.com/vf3BJZq.png
You could try asking to the Manjaro people, it works just fine in ArchLinux
I made a bug report to the Manjaro folks, will see what they say: https://forum.manjaro.org/t/okular-doesnt-provide-reason-for-failure-to-open-file/128499
