Thank you for your message.  Ever since I discovered this bug I have not
been successful at installing these 91 updates.  I think I reloaded package
information fron Synaptic Package Manager but I'm not absolutely certain
because I am very new to Ubuntu and Linux.  Would you please detail for
everyone how one goes about reloading package information from Synaptic
Package Manager?   I want to make sure I did this procedure correctly.
Thank you very much.
