[Users] ET Somerville configuration issue

Hello all user,

I am installing Einstein toolkit Somerville (2015) on Ubuntu-20.04. The download encounters an error in the configuration and compilation through 'SImfactory' and leaves the config folder inside the Cactus empty.

Command: "./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th"

Error: CalledProcessError:

Command 'b'./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th\n'' returned non-zero exit status 2.

Do help please.

Thank you
