verify integrity of installed packages

[fa2k]

Hi, I am experiencing some strange behaviour with sound, and I have been messing around with installing some ALSA drivers. I suspect that I might have corrupted some part of the installed Ubuntu packages.

Is there a way to check all the packages on the system for integrity using apt-get or similar?

Install debsums

sudo apt-get install debsums

Debsums will verify the files on your system against the files in the package repositories (and tell you if they differ)

Most packages include the neccessary info to verify them against the repositories, but some don't, so first up, run

sudo debsums_init

This will generate file hashes for any packages that lack them (note, this involves downloading the package from the repositories)

Then you can run the verification

sudo debsums -c

Thanks, that command is absolutely brilliant! (Found some things, but i don't think that was the problem)
