Verify all installed ubuntu packages

I dist-upgraded to Ubuntu 14.04 Trusty Tahr today, and at the end it said something went wrong and didn't install correctly and my system may not be stable state or something. Anyways before I rebooted I wanted to check if all the packages were installed properly. With a little googling I found the following gem on the ubuntuforums that I had to share (hello future self!).

Re: verify integrity of installed packages

Install debsums

Code:

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

Code:

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

Code:

sudo debsums -c

Lucky for me all were fine and I'm typing this after rebooting \o/ .

And the reboot was quite snappy!
