It gets an error at the very end:
INFO: Computing changes...
ERROR: resolve is unable to satisfy package requirements.
The problem was detected when trying to find a feasible version
for package NullableArrays.
However, this only means that package NullableArrays is involved in an
unsatisfiable or difficult dependency relation, and the root of
the problem may be elsewhere.
