Public bug reported:

I have two Vagrant boxes: one with Ubuntu 18.04 LTS, one with Ubuntu
20.04 LTS.  Both currently refuse to install libssl-dev for me:

vagrant at ubuntu2004:~$ sudo apt install libssl-dev
Reading package lists... Done

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
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.1 (= 1.1.1f-1ubuntu2.4) but 1.1.1f-1ubuntu2.5 is to be installed

(The 18.04 box is in a similar situation.)

packages.ubuntu.com says that libssl1.1 1.1.1f-1ubuntu2.5 is the current
version available in focal-updates.  I'm pretty sure my VM here doesn't
see it because of apt's phased updates (but I only know this because I'm
following the blogs on Planet Ubuntu; the error message give no clue!).

I have no idea how to resolve this in a generic way (it's an Ansible
playbook that fails for me).  As a manual fix, I suppose I could
downgrade libssl1.1 to 1.1.1f-1ubuntu2.4, but I don't want to hardcode
specific version numbers -- I expect 1.1.1f-1ubuntu2.5 will be available
universally some time soon?
