I started a new EC2 instance on us-east-1 Virginia using torcloud about 20 minutes ago.
When I do:
sudo apt-get update
I get:
N: Ignoring file '10periodic.bkp' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension
N: Ignoring file '50unattended-upgrades.bkp' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension
I wonder if it's normal or if it could prevent the unattended upgrades to work properly.
