Dear Maintainer,

   * What led up to the situation?: I ran `sudo apt update`, then `sudo apt upgrade`
   * What exactly did you do (or not do) that was effective (or
     ineffective)?: I tried `apt install -f`, tried to uninstall and
     reinstall nvidia-driver-full
   * What was the outcome of this action?: When I run apt update, it
   * finds the packages for version 550.144.03. However, apparently the
   * actual package versions in the testing repositories is 550.163.01,
   * and yet apt refuses to fins these packages. My Debian.sources is:

Types: deb deb-src
URIs: https://deb.debian.org/debian
Suites: testing
Components: main contrib non-free non-free-firmware
Enabled: yes
Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg

   * What outcome did you expect instead?: I expected `apt update` to
   * actually find existent packages in the repositories.

Managed to fix by replacing "testing" with "trixie," but surely I'm not
supposed to randomly need to change my "Suite?"

Maybe deb.debian.org resolved to a mirror that was not yet updated or
some cache delivered an old Packages file (the nvidia stack only
migrated yesterday). Switching the suite forced refetching the Packages
files (from a different path) which got you the latest version.


Closing this bug report as it seems to be an unfortunate timing issue.
If it happens again and frequently, it should be investigated further as
a mirror issue.
