how to clear cache in ubuntu

Caches can slow down your system when they are full. Clearing them might help speed up your Ubuntu machine. Here's how to do it. Open your terminal, you can do this by searching for it in your applications or using the shortcut Ctrl+Alt+T.

Great! Now, to clear the application cache, which stores temporary data for your applications, use the command 'sudo apt-get clean' and press enter.

When you use a command with 'sudo', it may ask for your password because it's executing that command with superuser (administrator) privileges. Type your password and hit Enter. You will not see any characters as you type, but that's normal. After the process finishes, your application cache should be cleared.
