[Bug 1787460] Re: Unattended upgrades removed linux-image-generic

Sat Mar 7 21:21:53 UTC 2020

Hi,

this bug still exists! It is IMPOSSIBLE to install linux-generic-
hwe-18.04 and virtualbox virtualbox-guest-x11-hwe virtualbox-ext-pack at
the same time. (arch i386)

I already reported this problem month ago here:
https://bugs.launchpad.net/ubuntu/+source/linux-meta-hwe/+bug/1856492

Seems like nobody cares! This is just pure shit! Some idiots think they
have to release kernel 5.3, but they don't consider that nothing will
work afterwards. What is even more stupid is that Kernel 5.0 is no
longer available! idiots! idiots! idiots! Damn, fix that!

How to reproduce this bug?
--------------------------

1.) create a minimal ubuntu with debootstrap

2.) use this sources.list:

deb http://de.archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://de.archive.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
deb http://de.archive.ubuntu.com/ubuntu bionic-updates main restricted universe multiverse
deb http://de.archive.ubuntu.com/ubuntu bionic-proposed main restricted universe multiverse
deb http://de.archive.ubuntu.com/ubuntu bionic-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu bionic partner

3.) update package lists

apt-get update

4.) install kernel 5.3.0 from bionic-proposed

apt-get install linux-generic-hwe-18.04

5.) install virtualbox

apt-get install virtualbox virtualbox-guest-x11-hwe virtualbox-ext-pack

---------------------------------------

actual result:

linux-generic-hwe-18.04 is being removed due to invalid dependencies

expected result:

linux-generic-hwe-18.04 keeps installed

Bug description:
  [Impact]
  If a user accidentally removed linux-generic, unattended-upgrades will also autoremove linux-image-generic, leaving them without kernel upgrades.

  [Test Case]
  1. Remove all reverse dependencies of linux-image-generic
  2. Mark linux-image-generic as automatically installed
  3. Run unattended-upgrades -v --dry-run --debug to ensure that linux-image-generic is not removed (after verifying that it is, with old apt)

  [Regression potential]
  This adds two regular expressions to the list of packages that must not be automatically removed. As such, the only possible regression is that some packages starting with linux-image, not containing any dots, are not removed

  [Original bug report]
  On a fairly fresh install of 18.04 with no modifications whatsoever to the unattended-upgrades configuration, it decided to remove linux-image-generic which also removed linux-modules-extra which caused sound drivers to disappear, etc.

  The relative snippet from /var/log/unattended-upgrades/unattended-
  upgrades.log is:
