Mark Logic server is, unbelievably, not supported on Ubuntu 8.10. However, the server runs just fine on that distribution. The following installation instructions might save you some time.

1. Create a temporary mark-logic directory somewhere and cd into that directory
2. sudo apt-get install rpm
3. sudo apt-get install alien
4. wget http://ftp.us.debian.org/debian/pool/main/l/lsb/lsb-base_3.2-23_all.deb
