This is what I get when trying to upgrade 10.10 Server to Natty.
$ do-release-upgrade Checking for a new ubuntu release Get:1 Upgrade tool signature [198B] Get:2 Upgrade tool [182B] Fetched 380B in 0s (0B/s) authenticate 'natty.tar.gz' against 'natty.tar.gz.gpg' exception from gpg: GnuPG exited non-zero, with code 1 Debug information: gpg: Signature made Thu 20 Oct 2011 10:58:12 BST using DSA key ID 437D05B5 gpg: /tmp/update-manager-bkM3OS/trustdb.gpg: trustdb created gpg: BAD signature from "Ubuntu Archive Automatic Signing Key <email@example.com>" Authentication failed Authenticating the upgrade failed. There may be a problem with the network or with the server.
I am using apt-cache proxy defined in /etc/apt/apt.conf.d/90-apt-proxy.conf
apt-get update/upgrade is working normally (using proxy apt proxy)
Server doesn't have direct Internet connection.
No X installed.

Any help will be appreciated.
