OK, I fixed a couple of bugs (see RTX-KG2 issue 186) and changed the script name (see commit cb685c7 ) and it should be working now, for either Ubuntu 18.04 and Ubuntu 20.04. Thanks for your help, @finnagin.

Confirmed to work for 20.04. Need to make a new instance to test on 18.04. @saramsey what size of instance should I use?

@finnagin I believe one can actually use a t2.micro instance to do a basic test of ARAX deployment; just make sure to allocate 200 GiB for the root filesystem storage. Of course, the t2.micro instance may not be able to run multi-hop queries and such, but I presume that's beyond the scope of the testing one would do specifically for issue 1751.

Hi @finnagin how is the testing for this issue going?

Verified to work on Ubuntu 18.04. I think we can close this issue.
