Hello everyone, Our library has been using a Vietnamized version of Koha 3.18 since mid 2014, running on Ubuntu server 14.04 LTS. No upgrade of the system has been made since and the server had a hardware problem (mainboard) last February. In an attempt to restore the Koha 3.18 database (a dump sql file of 1.8 Gb), I installed Koha 19.11 on an Ubuntu 16.04.6 LTS Desktop with a LAMP stack. After consulting with the mailing list yesterday, I followed the steps that were indicated, i.e Drop the 19.11 koha_library database, recreate it empty and then import the Koha 3.18 database sql dump file. Then I went to the staff login page http://localhost:8080 where I was welcomed by the login window for the web installation. I followed all the steps with success although at the crucial one (starting upgrading from 3.18 to 19.11) I had a Server timeout after 10-15 minutes waiting. I repeated the start upgrade procedure and was met again with a server Timeout. Then I had to go to work. At my office, I used the Easykoha Live DVD to install Koha 16.05 along with Ubuntu 14.04 LTS on an experimental partition. I then followed the same procedure as described a bove to do an upgrade of our Koha 3.18 database towards Koha 16.05. This, because the structure between the two database versions did not seem too differ too much (only two more tables in the 16.05 version). The upgrade from 3.18 to 16.05 was not successful though and I had a full web page filled with the errors that were met. When I came back home, I had the nice surprise to see that the upgrade from 3.18 to 19.11 had succeeded as I was welcomed by this message: "Updating database structure: Everything went OK. Update Done" and a blue button telling "Continue to log in to Koha". After clicking the button, I had a display of "Software error" that said: DBIx::Class::Storage::DBI::_dbh_execute(): Unknown column 'me.anonymized' in 'field list' at /usr/share/koha/lib/Koha/Objects.pm line 93 The line 93 (in bold below) is part of a subroutine as follows: sub find { my ( $self, @pars ) = @_; my $object; unless (!@pars || none { defined($_) } @pars) { *my $result = $self->_resultset()->find(@pars);* if ($result) { $object = $self->object_class()->_new_from_dbic($result); } } return $object; } Any hints on how to solve this problem would be greatly appreciated. Thanks for your attention and help. Quynh ================= M.
