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 '9004'.
Do you want to continue?
Continue [yN] y

Starting additional sshd
To make recovery in case of failure easier, an additional sshd will
be started on port '9004'. If anything goes wrong with the running
ssh you can still connect to the additional one.
