I've tested this fix by upgrading from wily to xenial with my mirror set to mirror.mcs.anl.gov. During the upgrade process my sources.list file was changed to the following:
# deb http://mirror.mcs.anl.gov/pub/ubuntu xenial main restricted universe multiverse # disabled on upgrade to xenial # deb http://mirror.mcs.anl.gov/pub/ubuntu xenial-updates main restricted universe multiverse # disabled on upgrade to xenial # deb http://mirror.mcs.anl.gov/pub/ubuntu wily-proposed main restricted universe multiverse # deb http://mirror.mcs.anl.gov/pub/ubuntu xenial-security main restricted universe multiverse # disabled on upgrade to xenial # deb-src http://mirror.mcs.anl.gov/pub/ubuntu xenial main restricted universe multiverse # disabled on upgrade to xenial # deb-src http://mirror.mcs.anl.gov/pub/ubuntu xenial-updates main restricted universe multiverse # disabled on upgrade to xenial # deb-src http://mirror.mcs.anl.gov/pub/ubuntu wily-proposed main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu xenial main deb http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse # auto generated by ubuntu-release-upgrader deb http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse # auto generated by ubuntu-release-upgrader deb http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse # auto generated by ubuntu-release-upgrader deb-src http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse # auto generated by ubuntu-release-upgrader deb-src http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse # auto generated by ubuntu-release-upgrader deb-src http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse # auto generated by ubuntu-release-upgrader # deb-src http://mirror.mcs.anl.gov/pub/ubuntu xenial-security main restricted universe multiverse # disabled on upgrade to xenial So this, and the fix for bug 1511783, looks good to me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1463680 Title: mirrors only added to mirrors.cfg, never removed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1463680/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
