The ubuntu.rst instructions for download-all do not work

[jwnimmer-tri]

I suspect that #2487 has broken the documented Ubuntu workflow.

On Ubuntu 14.04 Trusty, following from_source.rst and then ubuntu.rst from a new from-scratch build gives me:

Did I make a mistake anywhere?

[jwnimmer-tri]

The work-around appears to be to build using ninja per #2555.

[jwnimmer-tri]

Assuming that this a true problem, and not an error on my part... besides first fixing the immediate defect, the second question is then how jenkins let this defect escape detection.

[liangfok]

I am seeing this error too.

second question is then how jenkins let this defect escape detection.

The pod-build mode is not tested by the CI system. See #2484.
