Bug#992225: Suite value change for buster package list causes apt-get update failures

[Kamal Ramchandani <kamal.ramchandani@robinhood.com>]

Package: apt
Version: 1.8.2.2

It seems that the for buster package list, the 'Suite' value was changed from 'stable' to 'oldstable' on Sat, 14 Aug 2021
Reference - http://ftp.debian.org/debian/dists/buster/InRelease

This is breaking apt-get update across hundreds of services that we use.

Error logs as follows
E: Repository 'http://security.debian.org/debian-security buster/updates InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
E: Repository 'http://deb.debian.org/debian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
E: Repository 'http://deb.debian.org/debian buster-updates InRelease' changed its 'Suite' value from 'stable-updates' to 'oldstable-updates'

One option for us is to use the --allow-releaseinfo-change flag. But, doing so across all services is disruptive and a time consuming effort.

I wanted to check if this can be resolved on the debian side by maintaining backwards compatibility in the package list.
