Paul, You're right. The current stable tarball includes: - Outdated INSTALL.ubuntu* files - Outdated misc/ubuntu.packages file All people that answered your questions is aware of that (we meet at IRC every day and have nice exchanges on that subject). We even fixed that problem, and it should be in future releaes soon (our workflow is not optimal sometimes, there have been more urgent issues to fix). What we're all saying is that you are right about that; and besides that, Koha runs flawlessly for of us on 64 bit servers, runnning on Ubuntu LTS distro (12.04 and 10.04). People just told you how to circumvent those issues. Regards To+ PS: Sorry for my poor english. PS2: I've struggled and got annoyed for the outdated docs, and even filled this http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=8478. You'll see Mark's work there.
