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?
i read somewhere they had some ddos attacks so you may just wait a few days and try again

Swapped out the malware filtering DNS Quad9 for whatever the default DNS is and it worked fine. Sure hope this doesn’t mean anything.
i just used a third-party mirror. found one that was better and faster than ubuntu’s own ever has been for me:
