How to configure apt in Debian Buster after release

tl;dr : run once apt-get update --allow-releaseinfo-change

What happens here, is that the local apt database remembered your package-sources "release-information" to be "busterAsTesting", and when updating now "busterAsStable" is returned.

This results in the error, and the indication, that you need to "allow the change of the release version information".

Luckily, apt-get has an option for that, aptly named allow-releaseinfo-change

When running apt-get with this option, it notices -as without- the version discrepancy (the N:-lines), but now accepts it as told to do, and then updates the local database.


  1. open synaptic
  2. in menu select settings-->repositories
  3. in tabs uncheck everything
  4. close the tabs and let it make the update
  5. open again the repositories dialog and check everything you want
  6. close the tabs and update again and it is OK

I suggest using

apt update --allow-releaseinfo-change

This was because apt-get update --allow-releaseinfo-change did not work for me.

I cant comment on the accepted answer above. So if all else fails, use my answer.
