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
