When I added my repository, I designated components as "free non-free," per maemo instructions, and it worked. Though don't ask me to explain what the "free non-free" designation means. Good luck.
Thankyou again. After making this change and a reboot, the update worked and downloaded an update to osso-xterm.
This update has corrected the backspace issue.
Thankyou for you patience in assisting me.
