Cannot start jail from 11.2-b3 using older release

[Jacob H. Weeks]

Every time I attempt to start a jail on an older release I get an error stating "Local variable 'addr' referenced before assignment.

Upon further inspection the error reads:

Code:

The above exception was the direct cause of the following exception:

I don't know how to translate this or fix it. Can anyone help?

Are you starting the jail from the new UI or the legacy UI? If the new UI, do you get the same error from the legacy UI?

Are you starting the jail from the new UI or the legacy UI? If the new UI, do you get the same error from the legacy UI?

I thought the old UI only did warden jails and the new UI only did iocage jails. Given this, how would they start the same jail from both UIs?

File "/usr/local/lib/python3.6/site-packages/iocage_lib/iocage.py", line 1628, in start callback=self.callback

Given this line, we are working with an iocage jail. Do you intend to have the jail set with a static IP or DHCP? Also are you trying to use VIMAGE/vnet? If I had to guess, the jails config.json file is failing to fetch a DHCP address and its just trying to start the jail without one. I don't know enough about jail startup with DHCP to be sure.

Can you provide the output of cat /mnt/iocage/jails/<YOUR JAIL NAME>/config.json?

Same problem here. In /usr/local/lib/python3.6/site-packages/iocage_lib/ioc_start.py:426 "ifconfig -f" is used to determine the ip addr of the jail, this is not a valid argument in freebsd releases before 11.0 .
If I modify as follows it works:
cmd = ["jexec", f"ioc-{self.uuid}", "ifconfig", interface, "inet"]
Maybe we could check for the release with "if userland_version < 11.0:" and based on this decide for one method...

By the way, the error logging has a problem, since "failed_dhcp" is set by except su.CalledProcessError without defining addr that is used in the error logging later on.

Just realized this was already fixed in the iocage repo for some time....
