I am trying to install libcurl3 in my system. libcurl4 is already installed in my system.

enter image description here

The problem is, installation process is removing my R installation with installed packages.

Is there any way installing libcurl3 without removing R? Some of the softwares I want to use require libcurl3.

  • If I remember correctly you need to install development package, not binary one. So for compilation of some R-package you need to run sudo apt-get install libcurl4-openssl-dev. – N0rbert May 28 '18 at 19:32
  • As you see in the synaptic screenshot, libcurl4-openssl-dev is already installed. I want to install viber that requires libcurl3. But it wants to remove my R installation. I am trying to find a way to install libcurl3 side by side with libcurl4. – hmhsl May 28 '18 at 22:17
  • It seems to be impossible because of the fact that both packages share one file /usr/lib/x86_64-linux-gnu/libcurl.so.4 (see file lists for libcurl3 and libcurl4). You can try to contact Viber support about your dependencies problem. – N0rbert May 29 '18 at 9:07
  • Just leaving (this solution)[askubuntu.com/questions/1030479/… here for those who want to install viber which depends of libcurl3. – hmhsl Jun 2 '18 at 20:32
