ssl - Certbot renew fails on server becase "E: Package 'python-virtualenv' has no installation candidate"

Question

I am trying to renew my certificate, that I generated using certbot.

I am running sudo certbot renew but I get this in the end:

Note, selecting 'python-is-python2' instead of 'python'
Note, selecting 'python-dev-is-python2' instead of 'python-dev'
Package python-virtualenv is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python-virtualenv' has no installation candidate

I googled and went through a lot of guides and forums, but no luck. Anyone faced this error and found a solution?
