I install FreeBSD-9.0-RELEASE in VMware 9.0,then I use the commands
Why did the error occur?

I install FreeBSD-9.0-RELEASE in VMware 9.0,then I use the commands
# freebsd-uodate -r 9.1-RELEASE upgrade
and # freebsd-update install
to update FreeBSD 9.0 to 9.1. When I install PKGNG by the command # pkg_add -r -v pkg
, it is successful. But when I use the command pkg
, the error occurred! And pkg cannot work to install software.Why did the error occur?
