How to unpack a .RAR archive on linux?

Question

linux

An archive in rar format, when unpacking or trying to view it with Ark, it says "error while extracting make sure there is enough space on the disk". Of course there is a place.
Tried to install unrar - complains that the package is not available, no installation candidate was found for it. I installed an unrar free archiver, stopped seeing the files inside at all, deleted everything, everything went the same way.
It also does not come out through the console (here maybe I'm writing something wrong).

Answer 1

Install (probably not installed by default. In any case, in Ubuntu it is):
sudo apt-get install p7zip p7zip-rar rar unrar
p7zip p7zip-rar- in case you want to unpack rar with it ...
And then, as Ex1st wrote to you above.

Answer 2

unrar filename.rar

Answer 3

what exactly do you write "via the console"? and what is the exact error
