I followed the instructions shown here: How to install Viber in Ubuntu?

wget http://download.cdn.viber.com/cdn/desktop/Linux/Viber.zip
unzip Viber.zip
cd Viber

All was fine, but the last command doesn't work:

$ ~/Viber/Viber.sh
/home/erik/Viber/Viber: 1: /home/erik/Viber/Viber: �: not found
/home/erik/Viber/Viber: 1: /home/erik/Viber/Viber: /home/erik/Viber/Viber: 1: /home/erik/Viber/Viber: ELF: not found
Syntax error: word unexpected (expecting ")")

If I write:

$ Viber.sh
Viber.sh: command not found

But Viber.sh is in the directory:

$ ls

I also got a Viber icon in Dash, but clicking on it does not open Viber

  • Try to re-download it. I can install Viber on my 64-bit xenial by following your instruction.

  • Can you try bash Viber.sh? I think Viber.sh is using dash shell, which might be causing the issue.

  • Could you please edit your question to include the output of file ~/Viber/Viber.sh; md5sum ~/Viber/Viber.sh; sh -n ~/Viber/Viber.sh? Thanks. Dec 16, 2017 at 20:34

The instructions you have followed is an old thread. Probably there might be some issue with the version. I recommend you to go to the official website for downloading the Debian package (Link).

After downloading, performing sudo dpkg -i file_name.deb will help you to install the package.

Note: Links are subjected to change and could be broken. Always refer the official website for confirming version of any package before downloading.
