There is no specific handling in apt for this, so where are you seeing
this? Is it possible you see this in a graphical update tool like
update-manager?
Your apt-get log looks correct.
What does apt-cache policy snapd say?

Title:
apt ignoring pin/block/hold files in preferences.d for snapd
Status in apt package in Ubuntu:
Incomplete
Bug description:
Did some upgrades on a new box on 22.04, and had previously removed
snapd and BLOCKED via a file in /etc/apt/preferences.d/
And this upgrade cycle REINSTALLED snapd! and the stupid FF snap! Had
to repurge it again!
I had done this previously, and it appears that apt or something is
IGNORING any pin/holds of snapd
I use preferences.d files as using:
sudo apt-mark hold snapd
This has never worked on any package, ever...
I have:
/etc/apt/preferences.d$ cat snapd
Package: snapd
Pin: origin *
Pin-Priority: -1
And that previously resulted in an error on apt in any attempt to
install snapd, including using -s... NOW it will still attempt to
install snapd!
I've tried several variants of this as well, which other 22.04 and
20.04 boxes have, same on 22.04, it will allow snapd install!
Did sudo apt-get update, apt update several times, rebooted several
times, had various levels of the Pin-Priority from -1 to -9999, still
will attempt to install snapd, versus the expected error
sudo apt-get -s install snapd
Expected error: Reading package lists... Done Building dependency tree
Reading state information... Done Package snapd is not available, but is
referred to by another package. This may mean that the package is missing, has
been obsoleted, or is only available from another source
E: Package 'snapd' has no installation candidate
20.04 boxes still seem to fail correctly with this pin file,.....
Checking my BASE VM IMAGE of 22.04 and this still works there, as its
not been touched, this pin file blocks snapd from installing as
expected... this is apt 2.3.15, updated one is 2.4.5....
If I pick ANY OTHER RANDOM PACKAGE out and use the same pin/block
file, and change the name to that package, it blocks it from
installing! Anything but snapd this works for!
1)$ lsb_release -rd
Description: Ubuntu 22.04 LTS
Release: 22.04
2) sudo apt-cache policy apt
apt:
Installed: 2.4.5
Candidate: 2.4.5
Version table:
*** 2.4.5 500
500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
100 /var/lib/dpkg/status
What I expect to happen? HONOR MY BLOCK on snapd! It works for any
random package chosen, EXCEPT snadp!
