Not a good idea -- libc6 is required by pretty much everything, and
force-removing it will end up in an unusable system.

You could try:

1. download the lenny libc6 package you want;
2. 'sudo dpkg -i' it.

Just please be aware that mixing Debian and Ubuntu packages is not
always a good idea -- in libc6's case, probably a real bad one.

(in Maverick, 'apt-cache rdepends libc6' lists 14k packages... in
other words, a good portion of what we ship.)

Some of these packages may have a depends clause on the specific
version of the official libc6 -- it is safer to check *before* you
force the install:

sudo dpkg -i --dry-run <the lenny libc6>

and then analyse the output, and decide on a course of action.

Cheers,
