I get this occasionally.
Seems to happen when one of the FlightAware mirrors has a corrupted file. Just wait a while and try again, hopefully you will then get a different mirror server and it will work correctly.
yeah I’ve been having this problem too, its been going on for 11 hours now…hoping it’ll be fixed soon, as i’m trying to get a new pi set up and this is getting in the way.
I’m trying to install this software for the first time, and I’m also experiencing this same issue with a potentially corrupted mirror. This is causing a blocker on the installation process. Digging through the forum history shows that this issue seems to spring up with some frequency, which is a bit worrying
This issue is fixed. Sorry for the trouble. Some people were getting an old copy of the apt release files depending on which Cloudflare instance you were hitting
