You make a good point about breakage when packages are downgraded. But it seems a little disingenuous for us to bend over backwards to make unsupported upgrades possible (adding a "software sources" menu item, putting PPAs in Launchpad, creating /etc/apt/sources.list.d/ and so on), then for us to walk away when those upgrades make systems unusable.
I also take your point that pain is an important way of communicating danger to users. But making a system unusable seems like pushing a man off a cliff to warn him about the dangers of falling. I would expect the message to be at least as effective if we had a GUI to say "warning: may cause breakage" on upgrade, "warning: breakage caused" on downgrade, and breakage evident from the loss of configuration data. If that's acceptable to you, and if C's blueprint idea seems okay, then I'll include the GUI suggestions in the blueprint. - Andrew -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
