A quick hack to verify hashes of all installed dpkg packages and report which ones doesnt verify. I found a broken header file on my harddrive today and wrote this to be able to quickly reverify all packages to identify if my / drive maybe is beginning to fail.
Intentionally without sudo to generate more output, also the vagrant package seems to have installed a broken checksum file:
