Greetings, While working on https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=16618, I had issues installing underlying Elastic Search libraries too. This is how I solved them, though this may or may not be the best way. --- BEGIN SNIPPET --- And in case you didn't have elastic search stuff installed: echo deb http://packages.elastic.co/elasticsearch/1.7/debian stable main | sudo tee /etc/apt/sources.list.d/elasticsearch.list wget -O- https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - sudo apt-get update cd ~ wget http://debian.koha-community.org/koha/otherthings/elasticsearch_deps.tar.gz tar xvf elasticsearch_deps.tar.gz cd es_deps sudo dpkg i lib* sudo apt-get install -f --- END SNIPPET --- GPML, Mark Tompsett
