I'm not sure if this is a dselect problem, or an apt problem or just a difficulty from following the debian potato upgrade path.
dpkg version: 1.4.1.6 apt version: 0.3.11 Running dselect and selecting 'upgrade' yields: [apt output...package lists loaded].. Reading Package Lists... Done Building Dependency Tree... Done Merging Available information E: Invalid operation dumpavail update available list script returned error exit status 100. Press RETURN to continue. This broke quite some time back (for me), but I never actually got around to posting a bug report about it. I've not shoved this into the debian bug-tracking system, yet, since I'm not yet sure which package is causing the problem. Both apt and dpkg have been upgraded several times since this began. I have six potato boxes on which this occurs. I have two more that work correctly. Colour me confused. Happy to provide any extra information that might be of use. D
