Assuming the package apt-transport-https is up-to-date on your computer, what you're seeing are not errors but probably the warnings mentioned in the bug's description, second-to-last paragraph.
Please refer to the bug's description, and please report details here if seeing something the description doesn't mention. I'll investigate.
