Vivid Unit: Debian bookworm

It is planned and we are currently working on it.

I am trying the update manually on the vivvid unit machine.

This is my "/etc/apt/sources" file now:

deb  http://deb.debian.org/debian/  bookworm main contrib non-free
deb-src  http://deb.debian.org/debian/  bookworm main contrib non-free
deb  http://deb.debian.org/debian-security/  bookworm-security main contrib non-free
deb-src  http://deb.debian.org/debian-security/  bookworm-security main contrib non-free
deb  http://deb.debian.org/debian/  bookworm-updates main contrib non-free
deb-src  http://deb.debian.org/debian/  bookworm-updates main contrib non-free

After "apt-get update" I try "apt-get upgrade" and furtheron "apt-get full-upgrade" with these results:

 sudo apt-get full-upgrade

The following packages were automatically installed and are no longer required:
  libcdio-cdda2 libcdio-paranoia2 libenca0 libldb2 liblirc-client0 liblmdb0
  libmng1 libsdl1.2debian libtalloc2 libtevent0 libvorbisidec1 libwbclient0
  libxvmc1 python3-ldb
Use 'sudo apt autoremove' to remove them.

Shouldn' t it upgrade the packages now?

There are still quite some work to do before migrating to Debian 12, and you can not use apt upgrade to do it right away.
