FreeNAS Web UI not responding

Our FreeNAS is running; I can login via ssh.

But the Web UI is not responding.

From How to restart web ui on freenas I tried service nginx restart which gave:

Performing sanity check on nginx configuration:
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful
Stopping nginx.
Waiting for PIDS: 2180.

Starting nginx.

then service django restart and got:

       kill -l [exit_status]
       kill -signal_name pid ...

GUI is still not working. Should I try reboot ? Or is there another way?

Solution 1:

In this situation:

1. Failed install as described https://bugs.freenas.org/issues/18273 (i.e. the GUI Update said 20% and then halted)
2. Can ssh in
3. Library errors for the following:
   • service django start
   • wget
   • beadm activate (Grub errors, flagged the older boot as R but never booted into it.)
   • freenas-update
4. No physical access, so no choosing with Grub at startup.

My libraries were messed up! The fix?

1. mount the previous boot image:

   $ mkdir /var/tmp/9.10.1-U4

   $ beadm mount 9.10.1-U4 /var/tmp/9.10.1-U4/

2. restore previous libraries: $ copy /var/tmp/9.10.1-U4/usr/local/lib/lib* /usr/local/lib

Now beadm activate works. Switch to previous version, reboot, and follow Ajedi32's instructions (delete the broken boot version, try the update again).
