Wasted a bit of time as the error messages are quite archaic and only mention FileNotFound and package/connection errors. Figured I'd give a heads up for other students who use arch/manjaro:

Make sure to first start docker manually, as this is not done on manjaro by default:
sudo systemctl start docker

As mentioned here:
docker/compose#7896

Minor correction in the exercise 11 notebook: I think the intended variable name for the variable $square is $double since we are doubling each value in the sequence rather than squaring it :).

%%rumble
let $sequence := 1 to 10
for $value in $sequence
let $square := $value * 2  // doubling operation
where $square < 10
return $square
