I read at https://ubuntu-mate.org/raspberry-pi/ the following:
NOTE! There are no predefined user accounts. The first time you boot the Ubuntu MATE image it will run through a setup wizard where you can create your own user account and configure your regional settings. The first boot is quite slow, but once the first boot configuration is complete subsequent boots are much quicker.
Does it mean that setting up an Ubuntu Mate linux on a Raspberry 2 is only possible with keyboard and display, and not possible with remote console (ssh)?
If it is possible, what should be done after applying the image on the card?
