Hello.
I've had trouble running Viber desktop app for too long. I finally got it working by replacing some of the libs.
Tested this under Puppy Linux Dpup Buster 64.
-Added libxcb-keysyms.so.1
-Replaced Viber/plugins/xcbglintegrations/libqxcb-glx-integration.so (from Debian)
I have put together an SFS. This will run as spot. Hope it works for you too.
Viber 13.3.1 https://drive.google.com/file/d/16O0TzA ... sp=sharing
edit: additional Information.
"Viber is a cross-platform voice over IP (VoIP) and instant messaging (IM) software application operated by Japanese multinational company Rakuten, provided as freeware for the Android, iOS, Microsoft Windows, macOS and Linux platforms. Users are registered and identified through a cellular telephone number, although the service is accessible on desktop platforms without needing mobile connectivity. In addition to instant messaging it allows users to exchange media such as images and video records, and also provides a paid international landline and mobile calling service called Viber Out. As of 2018, there are over a billion registered users on the network"
