New Sap Instance not working. No instance profiles found - sap

Question

I have installed sap server 7.51 on ubuntu virtual machine (vmware). Installation was sucessful but when I run start I get the following error:
ubuntu:npladm 1> startsap all
No instance profiles found
please send the tracefile /home/npladm/startsap.trc to support
I typed ifconfig and got the following:
ens33: flags=4163 mtu 1500

I checked that the ip address in the host file is correct as in:
cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 ubuntu
# mapping the Ubuntu loopback IP 127.0.1.1 to ubuntu
192.168.234.130 ubuntu ubuntu.dummy.nodomain
# The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
127.0.0.1 localhost
127.0.1.1 ubuntu
# mapping the Ubuntu loopback IP 127.0.1.1 to vhcalnplci
127.0.1.1 vhcalnplci vhcalnplci.dummy.nodomain
As you can see the ip adress should be correct (192.168.234.130) and is pingable but it is still not working.
Update:
Here is also the trace log file:

Any other ideas about the error and how to resolve it? Thanks.

updating the ip-address of my VM in /etc/hosts helped:
> sudo nano /etc/hosts
..
192.168.1.218 vhcalnplci vhcalnplci.dummy.nodomain
.. then i started server
> startsap ALL
.. and checked that instances are running
> sapcontrol -nr 00 -function GetProcessList
