Whoops, I was fixing some issues with how we handle ESTALE yesterday
and managed to introduce those; looks like the standalone repository
got updated in the few hours they went unfixed. The upstream unstable
is already working and Sage is going to pull them into the standalone
repository now so they should be fixed later today if you update. :)
