Last software update of OS X Lion: the system freezes before the end.

Question

I was doing the last update of OS X Lion on a MacBook Pro (10.7.3). Before the end of the process, the system freezed. The only solution was the off button of the desktop. But after it was impossible to open it again. I had to restore OS X from the Time Machine backup. Can you help me? What is the problem? What do I have to do?

Answer 1

Just fixed this myself.
SWUPD is expecting a directory within the one you chose, called "html".
Example: /Volumes/XSAN/SWUPD/html
It will not create "html" if the directory doesn't exist.
Create the folder "html" then in terminal do this:
sudo chown -R _softwareupdate:_softwareupdate /path/to/the/folder
Example: sudo chown -R _softwareupdate:_softwareupate /Volumes/XSAN/SWUPD
##do not include/html. the -R means recursive and forces the same ownership on all contained directories.
