I tried to install systemd-container on brand new ubuntu 20.04 but I have following message:
sudo apt-get install systemd-container
Reading package lists... Done
Building dependency tree
Reading state information... 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.
But it's not obvious how to fix it because when I try, getting this
sudo apt install systemd=245.4-4ubuntu3
Reading package lists... Done

Reading state information... Done

The following packages have unmet dependencies:
policykit-1 : Depends: libpam-systemd but it is not going to be installed
systemd : Depends: libsystemd0 (= 245.4-4ubuntu3) but 245.4-4ubuntu3.2 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
And so one till libpam-systemd
sudo apt install libpam-systemd=245.4-4ubuntu3

And at this point, we got a circle.
EDIT: found that I can
$ sudo apt download systemd-container
$ sudo dpkg --force-all -i systemd-container_245.4-4ubuntu3_amd64.deb
And it's working but I got dependency errors all the time.
Is there any better workaround?
EDIT 2:
apt-cache output
apt-cache policy systemd systemd-container
