If somebody is still interested in snap for more recent julia version, I’ve created a snap for current stable 1.3.1. It is named julia-mrcinv and is built from this snapcraft config. The name of the executable is julia-mrcinv but it can be linked to julia by putting snap run julia-mrcinv into a script or using alias.
I do that too, but on my previous laptop that was not feasible due to hard drive limitations imposed by my employer. Also students often find themselves in a situation in which ther computer environment is constrained in various ways, making compilation and certain ways of installing software difficult.
