Tacking on a '-type f' like you suggested (and perhaps even a '-delete' to skip the xargs bit) would likely do the trick. > $ find /etc/mail -maxdepth 1 -size 0 > $ find /etc/mail -maxdepth 1 -type f -size 0 rak@zeta:~$ find /etc/mail -maxdepth 1 -size 0 /etc/mail/m4 rak@zeta:~$ find /etc/mail -maxdepth 1 -type f -size 0 rak@zeta:~$ > The first should output /etc/mail/m4, the second should output nothing. Your hunch on the error was right. I tried adding "set -x" to the top of the prerm file, and got the following output: rak@zeta:~$ sudo vim /var/lib/dpkg/info/sendmail-base.prerm No protocol specified rak@zeta:~$ sudo apt-get remove sendmail-base Reading package lists...

The empty directory shows up with size 0. What filesystem do you use for / ? The error should be triggered by this line in the prerm: # Remove empty files (probably touched databases) find /etc/mail -maxdepth 1 -size 0 | xargs -r rm; Please run these two commands: $ find /etc/mail -maxdepth 1 -size 0 $ find /etc/mail -maxdepth 1 -type f -size 0 The first should output /etc/mail/m4, the second should output nothing.
