Unable to install many packages in 2.0.1

[clauded]

Upgraded from 2.0 to 2.0.1 and I lost many packages during the upgrade. For example SQUID or NRPE wont install. Seems like files are missing on the freebsd servers (directory packages-8.1-release is non existant) :

pkg_add -r squid

Error: Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/Latest/squid.tbz: File unavailable (e.g., file not found, no access)
pkg_add: unable to fetch 'ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/Latest/squid.tbz' by URL

With the gui, seems like the files are not found either :

I also tried this without success :

pkg_add -r http://files.pfsense.org/packages/8/All/squid-2.7.9_1.tbz

Error: Unable to get http://files.pfsense.org/packages/8/All/squid-2.7.9_1.tbz: Operation not permitted

I rebooted the server and now I can install those packages  :o

This will remain a mystery!
