This seems like a really straightforward problem, but I haven't had much luck looking around the internet so far. (A couple message boards are talking about it, but they don't offer any solutions.)
When I run
sudo portsnap fetch, I get:
Looking up portsnap.FreeBSD.org mirrors... none found. Fetching snapshot tag from portsnap.FreeBSD.org... failed. No mirrors remaining, giving up.
- The internet connection appears to be working.
- I've successfully used
portsnap fetchon this machine before.
I'll obviously provide any other details you need, but I don't have any idea of what details would be relevant.
