Installation of Viber to Ubuntu 18.10 fails somehow. Had downloaded viber.deb from the viber.com, pressed Enter, got nice program instllation window in Ubuntu Installer with Viber’s icon and info about, pressed Install, autentificated this installation, got progress bar with 0% and… nothing. Back to installer’s Viber info screen. Something wrong with the package, or what? Please advise what can be done.
This seems like a Support question, so I’ll refer you to the support venues for it. This particular site is more about coordination and discussion of the Ubuntu project. Sorry.
