I had Solr 4.9.1 installed and I wanted to install the current version 5.3.1, which using Solr as a service, while 4.x version was using jetty. I tried to uninstall it the normal way
sudo apt-get purge jetty Package 'jetty' is not installed, so not removed
find / -name jetty getting a list of folders and files, so I had to remove the following files manually
/var/solr /opt/solr-4.9.1 /opt/solr /etc/init.d/solr /etc/default/jetty /etc/init.d/jetty
Using apache guide to install Solr 5.3.1, I am getting
Cannot execute /sbin/false error at the end of installation and also if I try to get it start
service solr start.
Do I have to add any environment variables? if not (as the guide mentioned), what am I suppose to do?
