i follow the admin guide to install onos and when i issue the following command:
sudo systemctl status onos.service
it output a error message that show failed to start open network operating system. However it seems like it failed to start due to the missing karaf (from the command tail /var/log/syslog line 2 and 3)?
thus I tried to create a symbolic link named karaf that points to the existing apache-karaf-3.0.8 directory under /opt/onos, the exact same error message still exists
I am using ubuntu 18 LTE Desktop version, if that helps
anybody able to help me with that
the following is what under my opt/onos directory:
maxyou@maxyou-virtual-machine:~/opt/onos$ ls -l
total 28
drwxrwxrwx 9 sdn root 4096 Dec 19 17:04 apache-karaf-3.0.8
drwxr-xr-x 174 sdn root 12288 Dec 19 16:59 apps
drwxrwxrwx 2 sdn root 4096 Nov 29 15:40 bin
drwxrwxrwx 2 sdn root 4096 Nov 29 15:40 init
lrwxrwxrwx 1 sdn root 21 Dec 23 20:19 karaf -> ./apache-karaf-3.0.8/
-rwxrwxrwx 1 sdn root 6 Nov 29 15:40 VERSION
i have attached a sequence of failed message from different commands
when use the command sudo systemctl status onos.service, it gives the following
maxyou@maxyou-virtual-machine:~$ sudo systemctl status onos.service

i have tried my best to show the error message from different perspective
can somebody tell me why sudo systemctl status onos.service gives error message and how to fix it?
thanks
