You can download the appropriate version from https://www.debian.org/releases/bullseye/releasenotes The warning is in § 4.2.1. It's recursive, so when you go back to buster's, it has the same warning (§ 4.2), and the same for stretch, jessie, and so on.

For example, you should update and upgrade the current version before you change sources.list, as the main upgrade should be made from the latest point-release. > 3. apt update > > 4. apt upgrade > > 5. apt full-upgrade > > But after my first edition to sources.list, apt update fails.

But do read the Release Notes (buster's in the first instance): if you follow them carefully, it's possible you won't get failures. I want to upgrade to Debian 10 (as a step to Debian 11), but I am having trouble with some signature. Let me show a full description. In my first try, I was not with an updated Debian 9. Someone asked me that, and then I tried to repeat everything after updating things. So, I 1. Restored sources.list to be what Debian 9 stretch uses 2. Asked 'synaptic' to reload the package database 3. Tried to do 'apt update' as root, but it does not work. GPG
signature error.
