Today, @isabelrios noticed a job that was marked as failed, even though every step passed. Based on this comment in travis-ci's issues, we might face unlogged cache failures.
This kind of error is usually not a problem, unless our shell scripts toggle
set -e
(and we do here, for instance).After looking up the documentation, we actually don't use the cache anymore. It started when we had to move away from the container infrastructure. Like said here, we won't be able to go back to containers until a few more months.
Consequently, I propose to save some CPU time and make the jobs stronger by just removing the cache.
