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.

Trying to update && upgrade but getting that error. I'm not sure how it happened but should I just manually add the DNS record for ports.ubuntu.com? I'm using pi-hole. I'm worried this is a MITM attack or some hacker trying to push malware. Does anyone have experience with this?
