[Bug 2041845] Re: Notifies about some ancient downgrades on every boot

[Mykola Yaroshenko]

- the complete message you see
Title is "Software updates Installed"
Body "Important operating system updates have been inst..." (truncated)

- the list of packages affected
There are only two: google-chrome-stable and mdadm

- the output of `apt policy $pkg1 $pkg2 ...` where $pkg1, $pkg2 and so on are the affected packages
google-chrome-stable:
  Installed: 118.0.5993.117-1
  Candidate: 118.0.5993.117-1
  Version table:
 *** 118.0.5993.117-1 500
        500 https://dl.google.com/linux/chrome/deb stable/main amd64 Packages
        100 /var/lib/dpkg/status
mdadm:
  Installed: 4.2-5ubuntu2
  Candidate: 4.2-5ubuntu2
  Version table:
 *** 4.2-5ubuntu2 500
        500 http://mirror.mirohost.net/ubuntu lunar-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     4.2-5ubuntu1 500
        500 http://mirror.mirohost.net/ubuntu lunar/main amd64 Packages

- the output of `apt list --upgradable`
apt list --upgradable
Listing... Done
this is irrelevant, notification shows on every boot regardless of if there is anything to install now or was installed on the last boot.

- the output of `/usr/lib/update-notifier/apt_check.py -p`
Nothing at all.

Added screenshot about downgrade part.

Title:
  Notifies about some ancient downgrades on every boot

Status in update-notifier package in Ubuntu:
  Incomplete

Bug description:
  Preparing for upgrade from 22.04 to 23.04 some packages were
  downgraded (or just marked as such?) and now update-notifier reminds
  me about them on every boot, this makes me likely to miss important
  upgrades available, because I tend now to dismiss it without looking.

  google-chrome-stable was upgraded many times since then, but I still
  get notifications about that 113.0... version. Btw, it says about
  downgrade from the current version!

  It's update-notifier/lunar,now 3.192.64 amd64
