I have recently installed openSUSE15.5 and Viber. The last was taken from viber.com and installed as # rpm -ivh --nodeps viber.rpm
As a result, Viber starts correctly, the chat is working, but the calls are not.
In the case of outcoming call, for me the things are as they should be: the chat is obscured with a splash screen and the long beeps are heard. At the site of the recipient, nothing happens. When I stop the call, there is no message about outcoming call.
In the case of incoming call, for the remote person everything is as usual, but nothing happens at my site. When after this I start to type text in the chat, I obtain the message about a missed call.
Here is the output of Viber started from the command line (the lines “# Start call” and “# Finish call” are added by me).
I have installed it from the Fedora .rpm file. I always do like this (at Leap 15.3 and earlier versions of openSUSE) and hitherto everything worked fine.
I’m not always a fan of flatpak, but before installing packages from another distribution which often leads to subtle problems i would definitely prefer the flatpak version.
Yes, I saw suggestions to overcome various problems with Viber through installation it with flatpak, but wanted to avoid this. And hoped that maybe simply some packages should be additionally installed.
As for me, it’s pity, that Viber cannot be now installed directly from viber.com. But maybe this is my preconceived attitude toward flatpak.
