I do not know. I thought only I had this problem, but for last two or three days (it worked like 5 days ago or so) it the extras repository isn't working for me too. Sometimes I get forbidden error, sometimes I can refresh it normally, but I can't install software from it when I try to do so from treminal. Try this in terminal and give us the output: pfexec pkg refresh
This command should, as far as I know, download latest list of available packages from repositories you have installed. If you need to install packages from other repositories and you want to use the GUI package manager, here is what you should type in terminal: pfexec pkg unset-publisher extras extras is the friendly name you gave to the extras repository. If you can't remember what it is open the Package Manager. It will be displayed in the repository list. The abovementioned command will remove extras repository from list of repositories available to you. Package manager should now be able to correctly refresh other repositories. This is not the final solution, but it should help until the extras is fixed. -- This message posted from opensolaris.org
