I can confirm this. Though the description of this bug is not quite correct, as has been commented already it effects all arch
For the moment you can workaround with the following; apt-get source dovecot-antispam cd dovecot-antispam-1.2+20090702 dpkg-buildpackage cd .. sudo dpkg -i dovecot-antispam_1.2+20090702-1_i386.deb (the build package depends on your arch). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/494162 Title: Incompatible filter on amd64 (lucid) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
