Comment 6 for bug 491027

So, what happened here is that as part of the auto-update branch we removed ubiquity's local fork of the updateInterface method on the grounds that python-apt had merged the fixes that made the fork necessary. It turns out we missed a bit, though, and that bit was needed to make things work right with non-blocking file descriptors. I'm testing a patch to python-apt to fix this; assuming that works, I think it would be better to improve python-apt than to reintroduce the fork.
