Ubuntu 20 Curl3 Installation
Ubuntu 20.04 aptitute sources are not supporting Curl3. If you need Curl3 like I do (unfortunetely) you can modify sources list and install over Ubuntu 18 (bionic) archive.
sudo nano /etc/apt/sources.list
Add below lines to the end (or wherever you want as new line)
#Ubuntu 18.X Repo deb http://cz.archive.ubuntu.com/ubuntu bionic main universe
Save and exit from edit.
Now you can update aptitude package cache and install
sudo apt-get update sudo apt-get install libcurl3 -y
