I've recently upgraded my OS from Ubuntu 16 LTS to Ubuntu 18.04 LTS and it's been a few days that the process unattended-upgrade is taking a lot of CPU power, forcing my fan to be quite noisy (cf screenshot)
Do you know what this process do, why it is always running and why it is so greedy in terms of CPU power? (What could it be possibly doing with all this calculation power?) Is it safe shutting it down?
Many thanks in advance for your help! :-)
EDIT: I tried to upgrade apt-get and i got the following message:
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
Can't use sudo anymore, could unattended-process be using sudo? if so why for so long?

This will help us gauge how old the other output is, – user535733 Nov 26 '19 at 17:04sudo /usr/bin/unattended-upgrade -dto see what it is doing – Jay _silly_evarlast_ Wren May 20 '22 at 19:49sudo killall unattended-upgradeuntil it was definitely killed. Then the update manager started correctly automatically and I was able to install updates without high CPU usage. – baptx Jun 09 '22 at 09:42
