[Freenas 9.2.1.7] Problem with pkg in Portjail

Hello,

since my update to Freenas 9.2.1.7 i have some problems with my portjail.

Everytime I use pkg, I got the message:
"pkg: PACKAGESITE in pkg.conf is no longer supported. Convert to the new reposit ory style. See pkg.conf(5) pkg: Cannot parse configuration file!"

Could someone please give some advice to solve the problem ?

Thanks a lot.
