I can verify that apt 0.7.9ubuntu17 in 8.04 is unable to add an intrepid iso image and that apt 0.7.9ubuntu17.1 in hardy-proposed is able to do so. Further tests of apt from hardy-proposed showed that it was able to do additional installs, updates, and dependency calculation, but more verification for regressions would be appreciated.
