After removing Viber version 5 from software center, and with

sudo dpkg --purge viber
sudo apt-get remove viber

I downloaded the version 6 viber .deb file from Viber's website, opened it and installed it with software center. When trying to launch Viber I get an error. And by running


in terminal, i get

[0425/170521:FATAL:browser_main_loop.cc(161)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on. Aborted (core dumped)

update: By running:


in terminal i get:

This application failed to start because it could not find or load the Qt platform plugin "xcb".

Reinstalling the application may fix this problem. Aborted (core dumped)

sudo apt-get install libqt5gui5

Run this in terminal and then reinstall viber.deb This resolves the issue.


I never use software center for installation, so I do not know how it handles .deb files. But maybe gdebi can help you:

$ sudo apt-get install gdebi
$ sudo gdebi viber6-XXX.deb

This will install all related dependencies.


For those who prefer to solve issues from the command line, simply run:

sudo apt-get install -f

...whenever a deb you've installed didn't have its dependencies resolved.
