When going to download or install something that takes much disk space, it’s better to first check if there’s enough free space left in your system.

Though the title said for Ubuntu, this tutorial works in most other Linux. The graphical way may vary depends on desktop environment, but the Linux command works in most, including Debian, Fedora, Arch, openSUSE.
