Невозможно установить systemd-container ubuntu 20.04

Я пытался установить systemd-container на совершенно новый ubuntu 20.04, но у меня есть следующее сообщение:

sudo apt-get install systemd-container
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 systemd-container : Depends: systemd (= 245.4-4ubuntu3)
E: Unable to correct problems, you have held broken packages.

Но это не очевидно, как это исправить, потому что когда я пытаюсь, я получаю это

sudo apt install systemd=245.4-4ubuntu3

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

И так один до libpam-systemd

sudo apt install libpam-systemd=245.4-4ubuntu3

И в этот момент у нас есть круг.

EDIT: обнаружил, что я могу

$ sudo apt download systemd-container 
$ sudo dpkg --force-all -i systemd-container_245.4-4ubuntu3_amd64.deb 

И это работает, но я постоянно получаю ошибки зависимостей.

Есть ли лучшее обходное решение?

EDIT 2:

apt-cache output
