hello today i tried to install viber the way you told me in the past
here but I find that it does not work referred to the problem below
The main reason is a library ,library libevent-2.1.so.7 not found,but the paradox is that it is installed...
viber

PS: The paradox is finally that the app image works, in relation to the old problem that didn't work.
