Hello Adam I am trying to reproduce the bug with current version of chkrootkit but i obtain a different result:
# sudo /usr/share/debconf/frontend /var/lib/dpkg/info/chkrootkit.postinst configure 0.53-1; echo $? # 0 I used a (still unreleased) 0.53-2 version and it seems to be correctly upgraded. Could you confirm this? Greetings, Marcos.
