Hi I think I've managed to install Koha now (not sure if it's successfully!) I installed CGI::Session (V4.30) manually as per the advice of this page: http://wiki.koha.org/doku.php?id=ubuntu_gutsy When I browse to the initial page http://localhost:8080 I get a "Production Mode - trapped fatal error" I also looked at this: http://www.nabble.com/Koha-3.0-beta-on-Kubuntu-gutsy---% 22production-mode---trapped-fatal-error%22-td17071451.html But not sure it was that helpful as already installed CGI::Session manually. Unfortunately I noticed these errors in my log (not the entire log file): [Thu Oct 16 15:06:36 2008] [error] [client 192.168.1.217] [Thu Oct 16 15:06:36 2 008] mainpage.pl: DBD::mysql::st execute failed: Table 'koha.language_descriptio ns' doesn't exist at /usr/share/koha/lib/C4/Languages.pm line 339.
