Why You want to upgrade from buster to sid? You have enabled both sid

I suggest to install sid from the scratch, if you want to have sid. If
you don't want to have sid, revert back to buster.
Also, sid doesn't have debian-security updates, this entry is invalid.
Most of this is correct, except for the part about installing sid
from scratch. That's not a thing. If one wants to run unstable, one
installs the current stable release, and then upgrades to sid.
