lektor jenkins builds fail randomly
this may be a duplicate of https://trac.torproject.org/projects/tor/ticket/30435 but maybe there are more reasons why builds fail with 'Undefined error'.
at the moment there are many errors on the jenkins builds, that are not related to the actual pushes to the repo. This amount of false positives makes people not to care about broken builds, and I guess it also wastes some human and computing resources.
please see a way to make jenkins not to fail for reasons that are not related to the code being submitted.
i have been saving some of the errors but they seem outdated and unaccessible now, i leave them as a grepping example: https://pad.riseup.net/p/jenkins-false-positives-keep
