As the title says, some packages which are required by Viber is missing. I am quite noob to Ubuntu. Can anyone guide me. Thanks

    Indicate Ubuntu version you are using. Not clear how you attempt installing Viber, because it likely is not in the default software sources for any version. – vanadium Jul 01 '19 at 13:53
  • Ubuntu 19.04... I tried installing using dpkg command – the newbie Jul 01 '19 at 13:55
  • Try sudo apt install ./viber.deb; it will automatically install all dependencies if they are available. – fkraiem Jul 01 '19 at 13:56
  • Got this error now ...

    The following packages have unmet dependencies: viber : Depends: libssl1.0.0 but it is not installable E: Unable to correct problems, you have held broken packages.

  • It means you are on 19.04, but the package you are trying to install is not compatible wth it (it requires libssl1.0.0, which is not available). You can try to contact the developers of the package to let them know about this issue, or just install 18.04 instead. – fkraiem Jul 01 '19 at 14:15

For some reason, as @fkraiem describes within the comments, the package libssl1.0.0 is missing in the Ubuntu 19.04's repository. Probably this should be reported as bug to Ubuntu's team. Fortunately, the good news is: you can download and install this package from 18.10's repository.

Go to the download page and click on the link security.ubuntu.com/ubuntu (located on the middle of the page), then an installation dialogue will be started. After that you can install Viber.

All together from the CLI:

sudo apt update

# download and install the dependencies
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu6.2_amd64.deb
sudo apt install ./libssl1.0.0_1.0.2n-1ubuntu6.2_amd64.deb 

# download and install Viber
wget http://download.cdn.viber.com/cdn/desktop/Linux/viber.deb
sudo apt install ./viber.deb

# just in case
sudo apt install --fix-broken

The original answer, that is proofed for Ubuntu 16.04 - 18.04:

The the last few times when I was installing Viber, I needed to install some dependencies manually by the option --fix-broken packages of apt... I just tried to install Viber on fresh Ubuntu 18.04 and encountered an error, but it is different from yours. The mentioned approach solved the problem again. Here it is:

sudo apt update
wget http://download.cdn.viber.com/cdn/desktop/Linux/viber.deb
sudo dpkg -i viber.deb
sudo apt install -f
