Today when i did apt-get -f upgrade i got this error:
(Reading database ... 42214 files and directories currently installed.)
Preparing to replace libc6-dev 2.0.7t-1 (using libc6-dev_2.0.7u-1.deb) ...
Unpacking replacement libc6-dev ...
dpkg: error processing libc6-dev_2.0.7u-1.deb (--unpack):
 trying to overwrite `/usr/include/linux', which is also in package
modutils
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
 libc6-dev_2.0.7u-1.deb
E: Sub-process returned an error code
 Does anyone know why i got such an error?  Also yesterday i believe i got
an error when trying to upgrade modutils something about the .deb not
being a regular file or it was corrupt.  Please help(tm).
Thanks alot.
