How to install curl on Ubuntu

curl is not installed by default on Ubuntu Desktop and other desktop variants of Ubuntu, such as Kubuntu. It is, however, installed on Ubuntu Server. That is logical as curl is commonly used for system administration and by power users, whereas normal desktop users would not need it installed on their systems.

curl package is available on both snap and apt for Ubuntu. Depending on your preference, you can install curl on your system using any of the two methods.

1. Launch terminal.
2. Update apt package list.

   $ sudo apt update
   [sudo] password for user:
   Hit:1 http://ports.ubuntu.com/ubuntu-ports jammy-security InRelease
   Hit:2 http://ports.ubuntu.com/ubuntu-ports jammy-proposed InRelease    
   Hit:3 http://us.ports.ubuntu.com/ubuntu-ports jammy InRelease          
   Hit:4 http://us.ports.ubuntu.com/ubuntu-ports jammy-updates InRelease
   Hit:5 http://us.ports.ubuntu.com/ubuntu-ports jammy-backports InRelease
