I have encountered a conflict with my gmail account password

What is your problem in the first place?

Thanks for responding. I cannot send from or receive emails into my Gmail account on my computer running Ubuntu. No problem on my iPhone or signing in on Gmail.com website. I can only think there is a conflict with the saved password saved on the smtp.gmail.com server. I will change it if I know how.
