Basically this is the problem I have:

When I go into app manage, I click on update. This takes about 5 mins to update but then I get the "some applications failed to refresh". So when i click in the application catalogues the maemo extras, extras testing and the extras devel repositories are all working fine, but the bottom two, namely "Nokia Applications and Nokia System Software updates" catalogues has the "failed to refresh" beside them with the (!) icon before it in red?

If i click either of these none working catalogues i get the catalogue details(which are filled in correctly) but at the bottom is some red text with "resolving host timed out: downloads.maemo.nokia.com"

here is the log after the repositories fail to update. The only one that does work is the extras
