Hi, I am running potato with 2.2.13 kernel. I screw up perl. So perl 5.004 is broken and cannot be removed. dpkg-preconfig is a perl script, so my upgrade failed. I try to the following command dpkg --purge perl-5.004 apt-get -f install It seems that apt-get depends on perl, and i cannot clean up perl 5.004 and perl 5.005 cannot be installed. Even I try to use dselect to remove perl-5.004, some error happened and perl-5.004 is still there. Any help will be appreciated! Jianbo
