/usr/bin/python3 /usr/share/unattended-upgrades/unattended-upgrade-shutdown --wait-for-signal on Linux

When I run htop and ps I see the following service running on my Debian server:

/usr/bin/python3 /usr/share/unattended-upgrades/unattended-upgrade-shutdown --wait-for-signal

Is this default and what is the purpose of unattended-upgrade-shutdown on Linux server?

unattended-upgrade is nothing but background service for automatic installation of security (and other) upgrades on a Debian / Ubuntu and other distros. In other words, it downloads and install security upgrades automatically and unattended. You can configure it via /etc/apt/apt.conf.d/50unattended-upgrades file. If I were you I leave it running. No need to mess it around. It is a security feature. For more info see my pages:
