I need some help with FireJail the first thing I need help with is how do I install it correctly on a Ubuntu based distro because the first time I used the Qapt Package installer but I got an error message after installing it this way, I recently tried to install again with dpkg but I don't think I'm doing something wrong here's what I did I downloaded the .deb file to my downloads folder and entered sudo dpkg -i firejail_X.Y_1_amd64.deb in the terminal got an error message. Can someone explain what I'm doing wrong and please give me a tutorial on how to install it the correct way.
You didn't specify what exact error message you got. Anyways, entering "sudo dpkg -i firejail_X.Y_1_amd64.deb" is defiitely wrong. Rather, you have to enter Code: sudo dpkg -i firejail_0.9.26_1_amd64.deb as this is the newest version from https://l3net.wordpress.com/projects/firejail/ .
Well I have successfully install it via dpkg command, in debian 8. please provide some more details about the exact error you are getting and just make sure you need to go to the directory, which held the downloaded .deb file in terminal via "cd" command, e.g. $ cd /Downloads
This thread has some useful practical info on setting it up etc https://www.wilderssecurity.com/threads/firejail-linux-sandbox.369309/
Thanks I'm still learning command lines the fist time I installed it I used Qapt and I forgot the error message it gave me, it was a while back but when I tried using dpkg it said something like invalid file location but I got it to work thanks to your help. So thanks
The second thing I need help with is configuring it, How do I use the private.keep feature do enter firejail --private.keep firefox in the terminal? Also I would like to be able to save my bookmarks/history, session, settings and downloads the default location.
