When I installed ubuntu 18.04 at first I was able to install Viber.deb file but after few re-boot, Viber stops working. I tried to search Viber in the installed list but I could not find. I tried reinstalling it again both:
and viber.deb but the software manager does nothing:(.
At last, I tried to install via wine/playonliux but the result is "one or more issues caused the setup to fail", so please help me to fix this problem.
