Comment 6 for bug 1924951

Are you talking about this question (see copy of the output in the terminal below)?

Reading cache

Checking package manager

Continue running under SSH?

This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.

If you continue, an additional ssh daemon will be started at port
'1022'.
Do you want to continue?

Continue [yN]

At this time I press N to stop.

However, this comes very early in my experience and the result is the same with and without the -p option. Last time I tried to upgrade the machine directly I also remember more stuff coming out in the terminal before the error occured.

Or is there another point later at which you can choose to upgrade or abort?
