Solaris 11.0 update to 11.1

Hi dear list,

I'm currently trying to update a Solaris 11 server to 11.1 SRU3 and
bump on this issue:

# pkg update --be-name s11.1 --accept
Creating Plan \                
pkg update: A signature in pkg://solaris/system/[email protected],5.11-0.175.1.0.0.23.1134:20120820T160256Z could not be verified for this reason:
The signature value did not match the expected value. Res: 0
The signature's hash is 235c7674d821032ae3eeda280c7837d1f1f4fdb5


I'm using a local package repository which is synced over Oracle Support repository,
but even getting rid of this repository and going through official oracle's one didn't help.

I was first in 11 SRU 10.4 and thought that maybe I should update first
to the latest SRU of 11.0, which worked, but then again, I can't get this
update command to go through.

Current version:

# pkg info entire
