$ sudo apt update

The APT package repository cache should be updated.

Installing CLion:

In this section, I will show you how to install CLion on Ubuntu. Let's get started.

First, navigate to the ~/Downloads directory with the following command:

$ cd ~/Downloads

As you can see, the CLion archive file I just downloaded is here. Remember the filename.

Now, run the following command to extract the contents of the archive to the /opt directory.

$ sudo tar xzf CLion-2018.3.tar.gz -C /opt

Once the archive is extracted, a new directory should be created inside the /opt directory as you can see in the screenshot below. Note the directory name.

Now, run CLion with the following command:

$ /opt/clion-2018.3/bin/clion.sh

As you're running CLion for the first time, you will have to do some initial configuration. Once you see the following window, click on Do not import settings and click on OK.

Now, select either the Dark theme Darcula or the Light theme. Then, click on Next: Toolchains as marked in the screenshot below.

As you can see, all the C/C++ development tools are automatically detected. Now, click on Next: Default plugins.

Now, you will be asked to tune CLion depending on what you do. For example, if you do web development along with C/C++, then you can keep the Web Development tools. If you don't need it, just click on Disable All, and web development functionalities will be disabled.

Once you're done, click on Next: Featured plugins.

Now, CLion will suggest you some popular plugins that you can install to add more functionalities to CLion. For example, if you work with GitHub, then the Markdown plugin is very important for you. So, you can click on Install to install it as CLion plugin. Once you're done, click on Next: Desktop Entry.

Now, make sure both of the checkboxes are checked. Then, click on Start using CLion as marked in the screenshot below.

First, start CLion and click on New Project from the dashboard.
