botched upgrade - can't upgrade or remove adept

[kshbaja]

i hadn't run my feisty machine in a long time and decided to fire it up last night. the first thing i tried to do was to update all my installed packages. i was having trouble with this for several different reasons including getting 404 responses for requested files from the mediabuntu repository. eventually i decided to upgrade to 7.10. this process seemed to hang at 99% in the fetching updates phase for a long time, leaving me no choice but to kill the process by closing the dialog box.

now, whenever adept tries to run, it core dumps with a segv fault. everything else still seems to work fine, but i can't do anything with adept. from the command line i have tried everything i found on the forum with no luck. each time i run one of these commands it coredumps when about 67% complete. i have a feeling that aborting the hung upgrade has corrupted the package database.

any ideas? i really would like to avoid a full reinstallation!

thanks in advance!

i can't even start up adept to try and change anything. any ideas on what i can play around with?

thanks!

Does it always stop at the same line? If so, try

$ kdesu kate /etc/apt/sources.list

and look for a bad line there. Then comment out the faulty line (or several lines) and run apt-get again.
