Hello @Kibahila i manage to install it
1st. but i think you should allow ubuntu firewall thing to allow Apache tomcat to work
2nd. other thing is try to check file called catalina.out use command tail -f tomcat-dhis/logs/catalina.out this can help you to see some errors also try to make a screenshoot and drop it here
Hey @Kibahila i have seen you are in Tanzania please send me your phone number so that we can share some knowledge because i’m just new also in using dhis2
