I have not used an image for installation. I did a debootstrap on a dedicated partition, installed a kernel and then rebooted.
Now I created a chroot environment in Lenny and reproduced the issue. Instead, if I try: # aptitude install uw-ipmapd I get: Setting up uw-imapd (8:2007 and ~ dfsg-3.1) ... WARNING: Port "imap3" unselected in debconf but possibly handled locally. Creating generic self-signed certificate: /etc/ssl/certs/imapd.pem (replace with hand-crafted or authorized one if needed) and the process stops indefinitely. I get the same result with an installation on VirtualBox. However I think the problem is not in the package tasksel, but in uw-imapd. So I was wrong to report here. Let me give you my apologies. Regards
