What is the preferred way to install Viber in a 21.10 desktop environment
In my previous ubuntu installs I've downloaded a deb for 12.04 from the viber website. From there I have needed to install some dependencies; not a biggie. But now I'm seeing viber in the snap store. I'm thinking cool, this should be easy.
"viber-unofficial" snap is missing a dependency on glibc 2.33. I thought snaps would include their dependecies. "viber-mtd" - Viber desktop support ubuntu. Doesn't seem to be doing anything.
When I try to install the deb from the viber website, I get the message "not supported" in the snap store application.
I'm running gnome. 21'10 flavor.

You have three download options:
AppImage from
deb-file from
Flatpak to install with the following commands:
sudo apt update sudo apt install flatpak flatpak remote-add --if-not-exists flathub flatpak install flathub com.viber.Viber
I find traditional deb-based method preferable.
I followed the recommendations from Viber webpage and it worked.
Then I had problem with the screen size, because the letters (fonts) were very tiny on the screen of my Ubuntu 20.04.4 LTS (Focal Fossa). After long time troubleshooting finally I found the right application file to edit. You need to modify the line in the viber.desktop file and set the resolution to your screen, adjust the value, it can be any small like 0.5 or anything higher like 1.5:
exec=env QT_SCALE_FACTOR=**1.1** /opt/viber/Viber %u There Viber.desktop files can be found at 2 places:
/usr/share/applications//home/username/.local/share/applications
When I edited the 1st file nothing happened.
When I edited the .local file, it changed to correct resolution!So set QT_SCALE_FACTOR to a good value in /home/<username>/.local/share/applications.
