Blindly upgrading can be dangerous and result in broken system, that's
why the Proxmox VE API only supports the interactive upgrade through
API using a html5 based shell to keep a (human) admin in the loop.
If your org evaluated the risk of doing this and is fine with that,
then I'd recommend using a lower level automation to frequently do
upgrades this way or setup unattended upgrades [0]. Adding this to the
PVE API signals to lesser experienced users that it's safe and stable,
which in our opinion it cannot really be (for those lesser experienced
ones).
So thanks for submitting a contribution, but we cannot accept this.

Still some comments inline.

If, this would IMO need dedicated permissions, sys.modify is rather overused
already and doing a system upgrade is certainly one of the most privileged
operations.

useless parameter, can always get added in the future if there would be the
need for such a property.

making this be quiet can make debugging errors after the fact much
harder.

This is not always guaranteed to be safe.

It happens in a worker task, what benefit has one silencing even more
output?

Message-ID: <99022DEC-C3F5-48FE-9F81-A262118D27F7@credativ.de>
Extend the PVE API by a new 'upgrade' path in the
apt path to perform 'apt-get -y dist-upgrade' on
the node in a noninteractive way to avoid blocking
the upgrade process.
