Teníamos un antiguo servidor Ubuntu 14, en el que instalamos certbot y ciframos certificados para SSL. Luego actualizamos el servidor a ubuntu 20.

He probado infinitos foros y trucos, incluido este gran éxito de Google ->https://stackoverflow.com/questions/62314556/how-to-install-virtualenv-on-ubuntu-20-04-gcp-instance, pero aún no hemos tenido suerte :( ¿Alguna idea?
