I just rebuilt, and it seems to be working. It’s a bit hard to tell
if the other sources are all updating correctly, because the
timestamps on the other sources aren’t updating to the current date
- I *believe* because there arent any new packages since their last
updates. The list updates quickly, and “U" gives me the expected
"nothing to update" response.
