It appears that it may be related to gem fetching as we've had successes and failures at the same time.

it's resolving pathspec 1.0.0 which doesn't work on ruby 2.5

[Bogdan Dobrelya (bogdando)]

actually, the problem seems in flaky connections to rubyjems

[Takashi Kajinami (kajinamit)]

pathspec 1.0 was released on Jan 5 but we have never seen this issue.
 https://rubygems.org/gems/pathspec.

As Alex pointed out, the problem is not consistent and I guess this is a temporal issue caused by unstable connection to rubygems.

[Michele Baldessari (michele)]

Ack, thanks folks. A bit unexpected that a network timeout would drive the dep decision, but it's okay if it's just a network glitch.
