Ubuntu 18.04 LTS was released five years ago. It has reached its end of life. If you are still using Ubuntu 18.04, you can either upgrade to 20.04 LTS or opt for Ubuntu Pro (free for three machines) to continue using it for five more years. You'll only get security updates if you opt for the Pro.

Let's see what else you get in this newsletter.

💡 Command Line Tips

To prevent files from getting overwritten while moving because of the same name, use this:

mv -n source_file target_directory

Another tip is to use the -u option. With this, the source files will only be moved to the new location if the source file is newer than the existing file or if it doesn't exist in the target directory.
