Jail stopped working after upgrade to 12.0-U6.1 with utf-8 decoding error

[RoughHeinz]

Hi guys,

I just upgraded to TrueNAS-12.0-U6.1 today and after the reboot my jail stopped working with the following error:
"Error: [EFAULT] 'utf-8' codec can't decode byte 0xc2 in position 454: invalid continuation byte"

I tried to start it from the commnd line via iocage and this ist what it threw at me:

Traceback (most recent call last):

I already tried to boot the box with an older working Kernel like 12.0-U6 o -U5 instead but it didn't solve the issue. So I suppose some config files are messed up. Obviously the utf-8 character encoding in a python script isn't properly set - but as I am not into phython, I am not able to help myself at the moment.

I'd be grateful for a hint.

Best regads

iocage get all <jailname> might provide a hint.

Thanks for your reply.

If I browse through the output of

iocage get all <jailname>

I'm just viewing the set options with nothing unusual. As the error occured by just updating from 12.0-U6 to 12.0-U6.1 I assume that those are OK.

Cheers,
Heinz
