Greetings

Basic question is: what happened?

I wanted to update a beowulf system.
So did the apt update, apt upgrade, apt dist-upgrade
after changing the references in /etc/apt/sources.list
from beowulf to chimaera.

After reboot - - - well - - - screen says devuan but
uname -r is 4.19.xx and not 5.10.xx

Any ideas as to how I update the kernel?

TIA
