'RVM says it is using 2.7.3, but ubuntu says i am on 2.7.0

Using Ubuntu, I ran the command

rvm use 2.7.3

I then ran

sudo rake db:create

and was greeted by the error

Your Ruby version is 2.7.0, but your Gemfile specified 2.7.3

Am I doing something wrong here? I have been battling with this for hours and have no idea how to proceed

The $PATH variable when using sudo is not the same as the $PATH for your non-sudo user. Because RVM works by modifying $PATH, the RVM modifications are lost when you invoke sudo. That's why RVM stops working with sudo.

If you really need to run something as root using RVM, then you can try it with rvmsudo instead.

You can read more here:
rvmsudo vs sudo?

Also check the manual for rvmsudo:
https://rvm.io/integration/sudo

However in your case it's better to adjust access to the database, so that root privileges are not needed for Rails to connect to the DB.
