Trouble upgrading Debian

Hello,

today, i started to upgrade my computer from Debian 9 (Stretch) to
Debian 11 (Bullseye). I had some trouble finding what i wanted to do, a
completely internet based upgrade, if possible. In the Debian
documention, i did not find this explanation. It says it can be done,
but it does not explain how to do it.

So, i opened the following thread. Do not read it now, there are more
things i will say here, first.

https://www.linuxquestions.org/questions/linux-software-2/upgrading-debian-distribution-4175700202/#post6281677

In the thread, I was advised to not upgrade from Debian 9 to 11 in one
step, because "jumping 2 releases will probably result in MASSIVE
breakage". This should be in the official documentation, no? If there is
this risk, it must be.

So, i should to 2 upgrades: one to Debian 10, and one more to Debian 11.
Fine. And for each one, the steps are:

1. Disable all third party repositories.

2. Edit /etc/apt/sources.list to reflect the next distribution i will
have. Directly, this is just changing all "stretch" occurencies to
"buster"; or all "buster" to "bullseye", in the second upgrade.

3. apt update

4. apt upgrade

5. apt full-upgrade

But after my first edition to sources.list, apt update fails. I have
tried apt-get update to, but it also fails for the apparently same reason.

What should i do to solve this?
