Update hanging on the install stage

I've just reinstalled Linpus on my AAO after a few months on Ubuntu. I tried to run the update and it failed a few times. I managed to get it going by using the instructions from Macles (http://macles.blogspot.com/2009/01/live ... blems.html).

Now it'll download all the updates (into a clean /var/cache/online_updater folder), but when it comes to install, the updater app just hangs on the first update (Keyboard layout settings 180045). When I run the updater from the terminal, I can see that it's hanging on :

runing sh /var/cache/online-updater/xkb_setting080816.sh
Verifying archive integrity... All good.
Uncompressing update xkb_settings.........
Preparing... ############## ( 33%)

I've left it for hours and it never gets any further.

If I try running the files by hand with 'sudo sh foo.sh' it does the same - hangs on the 'Preparing' line, but without the progress counter.

Any ideas?
