libtorrent-rasterbar9.so

Your system is using the wrong packages, which could be due to a botched upgrade. Reinstall the from the official PPA and/or fix other package problems in your system (you might have to remove old versions by hand, for example of boost, libtorrent, etc).

In general it is not recommended to upgrade major versions of Ubuntu due to package breakage like this being extremely common, it is better to just backup your important files and clean install.

I'll close this since this is not an issue with qBittorrent, but I'll leave it unlocked in case someone wants to help you out (though this is more of a support question for the forum, or better yet, an Ubuntu-related forum).
