Weird apt error

[Tiarnan O Corrain <ocorrain@esatclear.ie>]

Hello all--

I'm getting a really odd error with a debian box I administer. Apt
seems to be broken, or at least missing some serious files. Any advice
would be most welcome.

        crhist95:~# apt-get remove gdm
        Reading Package Lists... Error!
        E: Unable to write mmap - msync (5 Input/output error)
        E: The package lists or status file could not be parsed or opened.

Cheers

Tiarnan
