I am currently using Ubuntu 14.04.1 server.
When issuing a:
sudo apt-get upgrade
WARNING: The following packages cannot be authenticated
This is a fresh install from an ISO that used to deploy 6 other VMs with. The only thing I am seeing is this VM because it is in a different location is pointing to a different server for updates.
I have tried reinstalling the VM 3 times. I have rebuilt the /var/lib/apt/lists directory. I have also tried updating the keys using:
sudo apt-key update sudo apt-key net-update sudo aptitiude reinstall ubuntu-keyring
The packages that it is trying to update are:
The following packages will be upgraded: accountsservice apport byobu gir1.2-glib-2.0 krb5-locales libaccountsservice0 libc-bin libc6 libgirepository-1.0-1 libgssapi-krb5-2 libk5crypto3 libkrb5-3 libkrb5support0 libpam-systemd libssl1.0.0 libsystemd-daemon0 libsystemd-login0 libudev1 multiarch-support net-tools openssl python3-apport python3-distupgrade python3-gi python3-problem-report screen systemd-services ubuntu-release-upgrader-core udev
After I click "y" this is what I get:
WARNING: The following packages cannot be authenticated! libc-bin libc6 libssl1.0.0 udev libudev1 libk5crypto3 libgssapi-krb5-2 libkrb5-3 libkrb5support0 libpam-systemd systemd-services libsystemd-daemon0 libsystemd-login0 multiarch-support net-tools accountsservice libaccountsservice0 libgirepository-1.0-1 gir1.2-glib-2.0 krb5-locales openssl ubuntu-release-upgrader-core python3-distupgrade python3-gi python3-problem-report python3-apport apport screen byobu Install these packages without verification? [y/N]
I am concerned that I am downloading compromised packages. Also apt-get update runs fine without any warnings.
