Installing Viber on Debian 9

If you try to install Viber on Debian 9 you will probably get the following error:

dpkg: dependency problems prevent configuration of viber: viber depends on libssl1.0.0; however: Package libssl1.0.0 is not installed.

This is cause because libssl1.0.0 is not installed be default and is no longer available through the repos.

To install it, go to, download the deb package from a mirror and install it.

sudo dpkg -i /path/to/libssl1.0.0_1.0*

Then install Viber:

sudo dpkg -i /path/to/viber.deb

Enjoy :-)
