Hai all,
I use Debian on my server since Debian Buster.This great and very smooth operating system, I love it. I also install and use in VMware Workstation. I install Debian Bullseye RC-2. The question is:
How exactly to upgrade from Debian Bullesye to Debian Bookworm, What should I do? It is enough only change all word bullseye in /etc/apt/sources.list then What next should I do? Please give clear step by step explanation in command, because I've search on the internet, still make me confuse.
If you like a smooth operating system, stay with Bullseye. Bookworm is Testing ie. a development release and will be flooded with eternal upgrades for a couple of years until its release as Stable. Each upgrade will risk breakage.
I would never install Testing on a server, but if you like danger yeah sure edit bullseye to read bookworm in your sources and run apt update then apt upgrade then apt full-upgrade. It may break just doing that.
You should add contrib to your main sources if you have non-free there, and there are no security upgrades for Testing.
Please in future post code text as text in CODE boxes rather than image.

Ooo...oke siap, I think this is misunderstand, I won't upgrade my Bullseye to Bookworm in my server. I miss to tell I just want to update Debian Bullseye to Debian Bookworm in My VM for testing and development.
Thank you very much for your explanation, I just want to confirm, Is this include replace word with bookworm in line contain bullseye-security?

As I said, security upgrades are not generally available for Testing. The repository exists so it won't cause a problem to include it but it will remain empty until after Bookworm is released as Stable. (There was one firmware package released there about 3 years ago, but generally nothing).
So yes, replace bullseye with bookworm there. Definitely do not leave it as bullseye.
Also comment out the deb-src lines unless you plan to build packages from source; it will save a few seconds during updates.

Oke siap mantap banget, I've upgraded Debian Bullseye to Debian Bookworm, the process upgrading is very very smooth,great OS I love it no error during upgrade. Thank you very much to Debian Developer and for the clue and explanation.
[sorry for bringing up an old post]
does the method mentioned here ( upgrading from Bullseye to Bookworm ) upgrade the Kernel too? for NVIDIA driver issues ( kernel compatibility ) i had to install Bullseye which comes with kernel 5.x. ( i didn't want to make a Franken-Debian Bookworm with Kernel 5 so i chose Bullseye). now what happens if i upgrade to bookworm this way? can i then choose between kernels at boot? or kernel 5 will get removed after apt upgrade / apt full-upgrade ?
