Hi folks, Due to a lack of Copious Free Time my VM in the US is still running Debian Squeeze and is set up to use squeeze-lts thus: deb http://http.debian.net/debian/ squeeze-lts main contrib non-free But it is complaining that: The following packages will be upgraded: apache2 apache2-mpm-worker apache2-threaded-dev apache2-utils apache2.2-bin apache2.2-common apt apt-utils 8 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Need to get 4404 kB of archives. After this operation, 426 kB of additional disk space will be used. Do you want to continue [Y/n]? WARNING: The following packages cannot be authenticated! apt apt-utils apache2-threaded-dev apache2 apache2-mpm-worker apache2.2-common apache2.2-bin apache2-utils Install these packages without verification [y/N]? n E: Some packages could not be authenticated Now we also have some Squeeze VMs at work and they are configured almost identically: deb http://http.debian.net/debian/ squeeze-lts main contrib and they do not have this same issue. Now at both locations they resolve to the same IPv4 and IPv6 addresses but my personal VM in the US is using IPv6 and the work ones are IPv4 only, so I added the v4 address to /etc/hosts on my personal VM and it doesn't make any difference. The only thought I have left is that they are anycast addresses that are hitting different mirrors (or someone is MITM'ing me) so do any Debian gurus have any hints? cheers!
