From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

duordfto report those correctly.sudo ncduallowed me to find a 72gb [long string of characterless]-json.log file and many 1gb+ files in /var/lib/docker/overlay2. I'm not sure what to do with this information or what's safe to delete but I'm getting somewhere.Nice. Glad you're on to something.
I can't help you with docker files as I don't use it, but, there's usually a way to find out who / what owns a file, so I hope docker utils can tell you if it's safe to delete
