Hi, I have experienced some three major issues in an attempt to install KOHA 19.11 in Ubuntu 16.04 Server. 1. After successfully creating an instance called "library", on checking the available instances created using "koha-list", the result returns a null value (i.e. no instance is visible). 2. Consequently, due to the above, the apache-related files required to be edited and access from the browser are not available. For instance, the ~/library.conf file is missing data. That is, editing the /etc/apache2/sites-enabled/library.conf, the file is blank with no information in it. 3. Also, I believe still related to the missing instance, trying to use the "a2ensite" command to enable the site returns an error message stating, "The instance library does not exist." So how can enable this instance, whereas checking the data in Mariadb, the koha-library database exists? Thanks in advance. Regards.
