Ok, this is a sample of the 'log' file immediately AFTER the above err:

"osso-application-installer 4.46, UI version 2
E: Failed to fetch http://openbossa.indt.org.br/canola/...el/Packages.gz 404 Not Found
W: Duplicate sources.list entry http://repository.maemo.org bora/free Packages

Hmm....where do you start..?
