Installation Help (Ubuntu)

Hello all, I’d be grateful for your help please.
I’ve tried this install 6 times now each with the same issue(s).
When running the final command I don’t get any “ready to serve” message. In fact, nothing happens.
When I navigate to the browser, nothing.
I noticed that tomcat wasn’t running so I’ve started it with ./startup.sh in its bin folder.
Now, when I go to a browser :8081 I just get a page telling me that tomcat’s running.
Any ideas?
I used the install steps here: https://docs.axelor.com/abs/5.0/install/source/linux.html

Hello,

Have you read this ?

Good Luck, I don’t know more.
