Is /var/lib/mysql the working directory (of your shell,
or some other process) when you try?  Make sure
that is not the case. "cd" away from it.

Is this a mountpoint? (Unlikely but possible)
Is mysql running?  A broken "remove" script may
fail to stop it properly first - if so stop/kill mysql yourself
before attempting removal.

Is there something else in the directory?
Have a look.  If you don't find anything worth having, what
happens if you do a "rm -r var/lib/mysql/*" as root?

If weird things happen, go single-user, umount /var, and
use fsck.  If /var is part of the root fs, run that fsck from
a cd-boot or boot into single-user, mount read-only, run
fsck, then boot.

Try removing the package again after emptying the directory
manually.  You may also want to try

dpkg --force-all -P mysql-server-5.0

But take the warnings seriously if you do so.

If you want to simply reinstall the package (someone deleted
an important file?) then do:

apt-get install --reinstall mysql-server-5.0

This should overwrite all existing files. Another option
is to use: dpkg -i package-file.deb
After an apt-get run, you'll find the .deb file in
/var/cache/apt/archives

As a last resort, consider using
dpkg -L mysql-server-5.0
to see what files this package consist of, then remove them manually.
Or pipe the output of the above command into some form of "| xargs rm"

Consider using "reportbug" to report the problems with this package.
