On my desk, I have a 20TB external hard drive, which is encrypted using LUKS. This is the default on Ubuntu when you choose to encrypt your hard drive during installation or when you format a drive using the Disks utility and choose encryption.

Have you ever tried installing a program on your Ubuntu and ran into error messages about unconfigured dependencies? Don’t worry; it happens to the best of us. For example, when you install a program, it might rely on other software packages to run correctly; if those dependencies are not met, the program won’t work.
