Repo access problems when trying unconditional update

Due to various problems I’m experiencing since upgrading KDE to4.3 I’ve decided to do a full unconditional update of my system. It was all going well until it got to 6% and came up with an error saying that YAST cannot access the installation media and to check whether the server is accessible.
The file it’s tripped on is
File ‘./i586/konqueror-plugins-lang-4.3.0-5.14.i586.rpm’ not found on medium ‘http://download.opensuse.org/repositories/KDE:/KDE4:/Factory:/Desktop/openSUSE_11.1/

and the repo url is
Index of /repositories/KDE:/KDE4:/Factory:/Desktop/openSUSE_11.1

I skipped the file but it’s coming up for every second file now.

Repos are:

retry - if it keeps failing just skip it.
It’s no biggie

EDIT:
Sorry. I see you did that.
If you have to abort. Don’t reboot, whatever you do.
But if you just sit for half an hour and wait and then retry it may come back to life.

Oops too late. I gave up and turned the system off. I seemed to boot up fine this morning so hopefully nothing got messed up. I’ll try the update again.

Can I continue working on the computer while the update is going on? It’s a ~3.6GB download and estimated time is 4 hours. I can’t really afford not to be working while that is going on. If not I’ll have to wait till the weekend.

Continue working is fine.
Sometimes things don’t work quite right, but that’s rare.

Great. Hopefully this will fixed the problems I’m having.
