apt-get/dpkg broken, will not install programs, dead-locked

Try removing common.dpkg-tmp not kenolaba.

I can't even touch or enter the kenolaba directory. Since the common--- folder is inside kenolaba, there's nothing I can do about it it seems.

The ISO passed the MD5 check before i burned it. I'm not asking that, I'm asking if there are any flaws or reasons why the file copy would corrupt or produce a bad copy. As in no error checking or something like that. The CD is from January, and it's not scratched up. It of course has small scratches, but aren't CDs supposed to last at least a year?
