Thanks for your prompt response. I could not update my Ubuntu before because of the reported error. Following your advice, I have since poked around & discovered that the error was caused by several outdated repositories enabled under 'Other Software' in Ubuntu's 'Software & Updates' settings. I have now disabled them and can update my Ubuntu to the latest release.
Thanks for your help.
