I wanted to backup my data before I proceeded to upgrading my Ubuntu, which requires you to login into the Ubuntu Single Sign On, however I am unable to recollect my password. Trying to use the forget password option, gives me an invalid email address. However if I use the same email for registering as a new user, it gives me as a registered email address, preventing me for registering using the same email. Can you please help?
Sorry File services on ubuntu One is discontinued.
Send an email to isd-support asking for a password reset.
Then find somewhere else to upload your image, you can create an account at MEGA
Then create account. Or find somewhere else USB device DVDs for your backup.
