I had used OpenSnitch (https://www.opensnitch.io/) on U. Mate 16.04 quite a while ago, but stopped because I didn’t manage to handle it (at least, not in the way I used Little Snitch on OSX the year before).
But I maintained an eye on GitHub to see evolutions : and at this moment it seems that the author is intensely working on it.
I then downloaded the source code (no package available), and then I find myself unable to install the required external libraries by myself…
Anyone here with an actual experience in installing it?
Thank you!!
