why do I see unattended upgrades warning when installing a module?

Question

when i install a module using apt-get, it installs successfully but I see the following message:

N: Ignoring file '50unattended-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension

What can I do for this?

Answer 1

You should run gconf-cleaner & bleach bit for cleaning

Also .ucf-dist should be removed
sudo rm /etc/apt/apt.conf.d/50unattended-upgrades.ucf-dist
