After fresh update it gives error Warden does not have a path set, please set one in the GUI.
In order to fix issue change as follow.

- _dir = None
+ _dir = "/mnt/<zpool>/Jails"

Next step is to run migration script.

/usr/local/sbin/migrate_warden.py -v -j <Jail_name> -p <zpool>

Select the appropriate version

iocage fetch
iocage upgrade backuppc -r 12.2-RELEASE

:!:When iocage pkg backuppc update does not work.

Check if file /usr/local/etc/pkg/repos/FreeBSD.conf using the correct ABI.
Once the version confirmed, run following commands in jail.

# pkg-static install -f pkg
pkg-static bootstrap -f
pkg update -f
pkg upgrade
