Hi Andreas,

I have the same issue and your guess is correct. The problem is that
Arago servers are down so "git ls-remote" is failing and this makes
the BitBake task to fail as well.

Now about the why is been used tag names instead of just commits IDs
so a "git ls-remote" call is needed, this is because some git trees in
arago are been rebased overwriting the commit IDs.

You may take a look to Robert P. J. Day email "[meta-ti] objections to
replacing git SRCREV tag names with actual	hash IDs?" [1] to get a
better understanding of this.

Best regards,
javier
