My job gets stuck on “Queued” and never makes any progress. After about 12 hours, the job fails on its own. The log only shows “null”
This happens if you request a nonexistent environment.
In this particular case,
dist: doesn’t accept a list – so you end up requesting something like
dist: '["bionic", "xenial"]'. You need to write:
matrix: include: - dist: bionic - dist: xenial
This fixed it. Thanks.
