Hi everyone,

Some of you may have noticed the following errors at the beginning when running `wazo-upgrade` from Wazo Platform older than 21.08:

```auto
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'
Upgrading wazo-upgrade
...

```

No need to worry: the error does not have any impact, since we deployed a hotfix for `wazo-upgrade` on 2021-08-16 working around the issue. Unfortunately we cannot hide the error completely, and this error will only appear once.

This error is caused by the recent release of Debian 11 Bullseye on 2021-08-13: Wazo Platform does not yet use this version of Debian, but Wazo Platform still relies on the Debian 10 Buster repositories that have changed their name to `oldstable`.

For more details about the issue, see [WAZO-2472](https://wazo-dev.atlassian.net/browse/WAZO-2472).

The good side is that Debian 11 Bullseye is finally released 🎉 ! And we’re looking forward to release Wazo Platform working with Debian 11!

Happy upgrading!
