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@ubuntu2004:~$ sudo apt install libssl-dev 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 or been moved out of Incoming.

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?
