i have been waiting for this so I could upgrade my Xubuntu 13.10 without a net connection. Unfortunately, it is still not possible to do a dist-upgrade from the optical media.
If you try to do a dist-upgrade from the optical media the option will be grayed out unless there is a net connection. And if there is a net connection the upgrade will completely ignore the optical media and download everything from the net. In fact, you can pop the optical media out of the drive and the upgrade will continue. In the past one used the alternate install ISO to do a dist-upgrade without a net connection. But after 12.10 the alternate install media were discontinued. Ubuntu has long had a very bad system for dist-upgrades. It proceeds by downloading a new package, installing it, then repeating for each of the hundreds of new packages. if you lose your net connection in the middle you can be left with an unbootable system. Contrast with other distros which download the files and do not begin the install until all of them are available on your hard disk. I have been told that if you lose your net connection Ubuntu will pause the upgrade, but that is not true if you need to reboot in order to restore the connection. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
