During my day job at CircleCI, I’ve noticed more and more users running into an issue. With the recent release of Debian 11 “Bullseye”, the maintainers made a change to the Debian 10 repositories that is causing a breaking issue.
Here’s the error you’d see:
| InRelease' changed its ‘Suite’ value from ‘stable-updates’ to ‘oldstable-updates
To fix it, you just need to run:
apt-get update --allow-releaseinfo-change
This will acknowledge the change that Debian made and allow you to continue to use Apt as normal. Depending on your circumstances, switching to Debian 11 would be a solution as well.
