I was having problems with the website project hosted at Sourceforge for exceeding Its bandwidth threshold and I decided to temporally disable the online repository.
I was looking for an alternative hosting to store the repository and then I also decided to migrate the blog to this website.
For use the online repository, you need to connect the PS3 to the internet, open a lxterminal and download the file:
Then, you can execute it:
sudo sh online-update-2011-09-23.sh
This update has been designed only for the RC 5 or lower and It will be included on the next release of the LiveCD.
