The mirror list is shipped in python-apt and updated with each python- apt update, and with each Ubuntu point release based on the launchpad mirror feed https://launchpad.net/ubuntu/+archivemirrors-rss.
Additional updates to just the mirror list are not made. The mirror method is supported using the official mirror://mirrors.ubuntu.com/mirrors.txt url. Additional urls are custom modifications and not recognized by aptsources as Ubuntu mirrors. It might be possible to make aptsources look at Origin field in the Release file if you have downloaded them, however that's prone to breakage if you switch releases, so it's not optimal. In any case this is not a bug in software-properties. Please open a bug against python- apt if you believe we have reasonable means of supporting unofficial mirrors like official ones. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814072 Title: software-properties-gtk does not recognize https mirrors under Ubuntu Software To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1814072/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
