I installed tomcat 8 on my ubuntu 18.04 system. Later I have downloaded geoserver web archive from geoserver page and deployed the war file on /var/lib/tomcat8/webapps. Tomcat is working fine before deploying the war file.[ localhost:8080] is working fine. But the problem I am getting is after deploying the geoserver war in webapps directory tomcat is not loading on browser.
