Okay, then this is most probably a packaging error in chakra linux (if you're using Inkscape 0.92).
(actually, it's also missing in my own, self-compiled version, now that I have checked...)
Now, it could eventually help to install potrace / libpotrace, if, and only if, the packager has compiled Inkscape with it, but forgotten to add it as a dependency (but I don't have much hope for it).
If you have installed libpotrace / potrace, and it still doesn't work, then you'll need to definitely make a bug report for chakra linux, or you can try to compile Inkscape yourself (from source), after installing libpotrace-dev and potrace (and all the other dependencies).
If you want to notify your packager of the issue, please point them to this link:
