@wifiuk I’d recommend strongly against using the system Ruby, except in cases where you’re deploying a system that’d not going to have users. While it is a bit more work, I encourage something like rbenv, which offers a user-centric Ruby environment.

At the very least, this will let you use the most up-to-date version of Ruby, instead of the one that Ubuntu packages, which is very likely to be quite out-of-date, and potentially insecure as a result.

That also means you won’t run into issues like this.
