Impossible d'installer les ajouts d'invité VirtualBox sur Ubuntu 18.04.2 LTS avec HWE - pourquoi?

Récemment, j'ai installé HWE sur mon Ubuntu 18.04.2 LTS fonctionnant dans VirtualBox. C'était une installation propre sans PPA et sans référentiels tiers. Quelques informations sont ci-dessous:

$ head -n2 /etc/apt/sources.list
#deb cdrom:[Ubuntu-MATE 18.04 LTS _Bionic Beaver_ - Release AMD64 (20180426)]/ bionic main multiverse restricted universe

$ hwe-support-status
Your Hardware Enablement Stack (HWE) is supported until April 2023.

Avant l'installation de HWE, j'ai installé virtualbox-guest-x11, mais maintenant il est supprimé. De plus je ne peux pas l'installer à nouveau:

$ Sudo apt install virtualbox-guest-x11

et un nom HWE aussi:

Que devrais-je faire?

Mise à jour: le bug a été corrigé le 2019-03-08 avec la version virtualbox-guest-x11-hwe 5.2.18-dfsg-3 ~ ubuntu18.04.3.

C'était un problème de dépendance, j'ai donc signalé deux bugs:

  1. bug 1816383 - Impossible d'installer virtualbox-guest-x11 sur 18.04.2 LTS avec HWE
  2. bug 1816386 - Impossible d'installer virtualbox-guest-x11-hwe sur 18.04.2 LTS avec HWE

Ainsi, la solution la plus simple sera d'installer le noyau ordinaire et Xorg, puis de supprimer les packages HWE

Sudo apt-get install xserver-xorg linux-image-generic
Sudo apt-get purge xserver-xorg-hwe-18.04 linux-image-generic-hwe-18.04 xserver-xorg-legacy-hwe-18.04 xserver-xorg-core-hwe-18.04 xserver-xorg-video-intel-hwe-18.04
Sudo apt-get autoremove

puis réinstallez virtualbox-guest-x11 avec

Sudo apt-get install virtualbox-guest-x11

Vous pouvez essayer de lancer

apt-get install --reinstall virtualbox-guest-x11-hwe
