PuTTY is a free and open-source cross-platform SSH and telnet client that even after being around for over 20 years remains one of the most popular SSH clients being used especially on the Windows platform.

The quickest reasons that come to mind for such scenarios include:

• Familiarity: users are more comfortable using an SSH client they got familiar with while using Windows.
• Debug mode: Connection to serial pots and raw sockets is more user-friendly with PuTTY.
• Convenience: PuTTY has a GUI that undeniably makes it easier to use especially by SSH and/or terminal newbies.

It is possible for your own reasons for wanting to use PuTTY on GNU/Linux are different. It doesn’t really matter. Here are the steps to take in order to install PuTTY on the Linux distro of your choice.

How to Install PuTTY on Linux

PuTTY is available to install from the default official repositories in most Linux distributions. For instance, you can install PuTTY on Ubuntu and its derivative distros via the universe repository.

Install PuTTy on Ubuntu and Linux Mint

First, you’ll have to enable the universe repository so that you can access its packages, update your system to recognize its new access rights, and then run the apt install command.

<code>sudo add-apt-repository universe
sudo apt update
sudo apt install putty</code>

Launch PuTTY to see that its UI mirrors that of the windows version. Happy you :-)

Arch Linux and its derivatives can also install PuTTY from the default repositories.

PuTTY is available to install via the distro’s default package manager such as yum or dnf.

<code>wget https://the.earth.li/~sgtatham/putty/latest/putty-0.82.tar.gz
