[Bug 2091906] Re: linux-headers-6.8.0-50-generic missing from Packages.gz in jammy-updates (observed in Podman container)

[Julian Andres Klode]

Installing kernel headers for the currently running kernel is not a
supported operation as they may no longer exist. The correct way to
install additional kernel packages is to install the meta packages that
pull in the latest version, upgrade the kernel to the latest version,
and reboot into it.

** Changed in: apt (Ubuntu)
       Status: New => Invalid

Title:
  linux-headers-6.8.0-50-generic missing from Packages.gz in jammy-
  updates (observed in Podman container)

Status in apt package in Ubuntu:
  Invalid

Bug description:
  While building a podman container image using "FROM ubuntu:22.04"

  The build encountered an error very early at step "RUN apt-get update
  && apt-get -y upgrade && apt-get -y install  [...] pkg-config linux-
  headers-$(uname -r)" with the following messages:

  ...

  E: Unable to locate package linux-headers-6.8.0-50-generic
  E: Couldn't find any package by glob 'linux-headers-6.8.0-50-generic'
  E: Couldn't find any package by regex 'linux-headers-6.8.0-50-generic'

  This container image build has been running seamlessly for several
  weeks before on different computers.

  After investigating in the repository "archive.ubuntu.com", I realized that 'linux-headers-6.8.0-50-generic' entry is not present in "/ubuntu/dists/jammy-updates/main/binary-amd64/Packages.gz", whereas other similar packages entries are present (eg 'linux-headers-6.8.0-49-generic' and even 'linux-headers-6.8.0-50-lowlatency').
  I also checked successfully that the package related to the missing entry is indeed present in https://ca.archive.ubuntu.com/ubuntu/pool/main/l/linux-hwe-6.8/linux-headers-6.8.0-50-generic_6.8.0-50.51~22.04.1_amd64.deb

  apt version is 2.7.14 (amd64) inside the container.

  This problem might be the root cause for the reported bug

  a handful of other issues reported lastly on the internet.
