Notably, there has been no related change of the mirror method since the trusty release. So if it started working later, than that is related to the reworked acquire system.
As such, I'd like this bug to be closed as invalid, as it's not worth it. The pre 1.1 acquire system cannot really deal with failures gracefully. You could of course try wily, if it works there, you're lucky, and can backport the fix. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1625667 Title: Trusty: apt does not try next mirror if index file download fails with mirror:// source Status in apt package in Ubuntu: Invalid Status in apt source package in Trusty: Invalid Status in apt source package in Xenial: In Progress Bug description: When using the mirror://mirrors.ubuntu.com/mirrors.txt functionality on Trusty, if the download of the index file fails, apt will not retry on another archive listed in mirrors.txt and will fail.
