    Try installing libcurl3 explicitly. Run sudo apt install libcurl3 and then try to install viber again – Kulfy Jan 5 at 6:49

    I tried to install libcurl3. I got this: sudo apt install libcurl3 Reading package lists... Done Building dependency tree Reading state information... Done Package libcurl3 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: libcurl4:i386 libcurl4 E: Package 'libcurl3' has no installation candidate – Prabesh bhattarai Jan 6 at 7:29

I recently made a script for that. Works in Debian and other Debian-based distros (Ubuntu 18.04 tested - working). The script installs libssl1.0.0 (dependency), fakeroot & gdebi for the installation and finally Viber itself.

The problem here is indeed the libcurl package (Viber requires libcurl3 but the OS already uses libcurl4, so there's your conflict).

We'll need to create 2 files (.sh) and make them executable.

touch viber.sh repackager.sh
sudo chmod +x viber.sh repackager.sh

Double click viber.sh and inside it paste this:

sudo apt-get install gdebi fakeroot
wget -O libssl1.0.0 security-cdn.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u10_amd64.deb
sudo gdebi libssl1.0.0.deb
wget -O viber.deb http://download.cdn.viber.com/cdn/desktop/Linux/viber.deb
sudo gdebi viber4debian.deb

Now, double click repackager.sh (it's important to name it "repackager.sh", otherwise it won't work) and paste this:

fakeroot sh -c "
  mkdir tmp
  dpkg-deb -R viber.deb tmp

  • Hey. Seems libcurl3 is missing. If for some reason apt-get can't find the package, you may use one of the options here. Either update your sources.list and try again or download the package manually through a net mirror on the link and install via aptitude/synaptic. Once libcurl3 is installed, everything should work normally. – Nick Tritsis Jan 6 at 14:35
