so in looking at this, it seems that the shell script data/apt-cdrom- check is responsible (used as helper script) for determining if the media contains a valid upgrade source, so that seems the correct place to fix this.
I'm not sure though what the best method to go about that would be. looking at an 11.10 cd, i see the .disk/info path contains some version/release information that could be used to make a comparison agains /etc/lsb-release on the base system, but i'm not sure if older releases also had the .disk/info on the install media, or if it would be preferable to carry an array of some md5's of the older media? i'm going to see about snagging some older ubuntu releases to look at and see whether .disk/info is even a good option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887650 Title: Upgrade to older releases To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/887650/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
