Postgresql-10 not found on ubuntu 20.04

On a fresh Ubuntu 20.04 installation I get the following error:

$ sudo apt-get install -y -qq postgresql-10
ERROR: failed to install postgres, try to install it manually
and then run again `python -m remo_app init`

solved it by manually running

sudo apt install postgresql

Thanks for reporting the issue @marco!

We will try to replicate it on our side and issue a fix.

This has been fixed now.
