Ubuntu 13.10 64 server, after doing one upgrade from 13.04 -> 13.10 then attempting 13.10 -> 14.04. I had a transient network failure downloading package lists for 14.04 once which stopped the process, trying to restart the process results in the following
root@server:~# do-release-upgrade -d Checking for a new Ubuntu release Get:1 Upgrade tool signature [198 B] Get:2 Upgrade tool [1,148 kB] Fetched 1,148 kB in 0s (0 B/s) authenticate 'trusty.tar.gz' against 'trusty.tar.gz.gpg' gpg exited 2 Debug information: gpg: fatal: can't open fd 6 for status output: Bad file descriptor secmem usage: 0/0 bytes in 0/0 blocks of pool 0/0 Authentication failed Authenticating the upgrade failed. There may be a problem with the network or with the server.
How can I restart the do-release-upgrade process?
Apt-get has been fully updated, upgraded, dist-upgraded.
