bst build seems to be stuck forever, not downloading anything
Summary
In the freedesktop SDK, we have a desktop-platform-image.bst element:
$ bst build desktop-platform-image.bst
…
[03:49:49][Pull:desktop-platform-image.bst]It usually takes me about an hour to pull the artifacts for this element (which I already find incredibly slow, but that might be #554 (closed)).
This time it's been pulling for almost 4 hours though…
Steps to reproduce
This is the first time it happens to me, so I don't think you might reproduce it easily.
But clone the freedesktop-sdk repo then:
$ bst build desktop-platform-image.bstIn case it helps, I'm on revision 4f415382919437f9f0b89037d893c4e6ff25031a from that repo (but I don't think it will help reproduce it).
What is the current bug behavior?
Buildstream is pulling, seemingly forever.
My ~/.cache/buildstream/ is not growing at all.
What is the expected correct behavior?
This should have finished pulling about 3 hours ago.
