Koha 3.8.4 on Ubuntu server 12.04 LTS including importing an existing 3.6.1 database. Finally got my trials and tribulations behind me, 3.8.4 up and running (now on to detail, customization and pre-production testing.) A couple of points following previous threads (YMMV, but this worked without a single error for me this morning): 1) Use ubuntu-12.04.1-server-amd64.iso (598,902,661 bytes) which replaces ubuntu-12.04-server-amd64.iso (717,533,184 bytes) -- I'm not certain what the hiccough was, but there have been considerable changes made. This latest ISO, much smaller than the previous one, allowed everything below normally. 2) Add the debian.koha-community.org/koha repository to /etc/apt/sources.list.d/koha.list before looking for dependencies. 3) Before using dpkg, dselect from the Koha .gz, $ sudo apt-get install libtemplate-plugin-htmltotext-perl zip unzip yaz idzebra-2.0 daemon dselect libyaz4 libyaz4-dev libnet-z3950-zoom-perl libxml-libxslt-perl libgraphics-magick-perl liblingua-stem-snowball-perl libtemplate-perl liblingua-ispell-perl libhtml-template-pro-perl libreadonly-xs-perl libtest-strict-perl 4) Koha will try to install (and report "missing/not required") DBD::SQLite2 which as far as I can tell is superceded by libdbd-sqlite3-perl (i.e version 3) which I installed. 'Make test' will report it, but 'make install' is fully functional. 5) After installing and configuring Mysql, Koha and Apache2, doing the following *in this order* allowed clean updating of a db restore, Zebra indexing and zebra incremental cron: a) Verify from a workstation browser: http://koha3 ==> OPAC (will report "under maintenance.") Do NOT YET verify http://koha-admin3 ==> Staff client login b) NOW restore a working copy of a working db: c) http://koha-admin3 ==> Staff client login will go through "upgrade" process d) Setup Zebra daemon at boot e) Reindex Zebra (auths and biblios) f) Set up cron Zebra incremental Thanks to all involved, best regards, Paul
