We recently saw an official desktop for Raspbian called Pixel, a lightweight desktop suitable for Raspberry Pi, at least more suitable than other desktops. But like all new software, Pixel has its holes and problems. The Pixel development team has released an update that will be quite problematic for some users.
This Pixel update solves certain problems that the desktop had in terms of security but It also disables the SSH protocol so communications cannot be established through it..
The update of the new Pixel desktop comes with the date of 25/11/2016 and has the numbering of 1.1. Important data to know if our operating system is really up to date or not.
The new Pixel update makes Raspbian more secure but also that we do not have SSH at the moment
The problem with the SSH protocol is that if we use this protocol to communicate regularly, after the update we will not be able to do so and we will have to be in front of Raspberry Pi to be able to enable it again, something that does not prevent the update itself as is logical.
The Raspbian team and the Raspberry Pi Foundation itself assure that the security problem was serious and that is why they have released this update, but in no case prevents SSH from being on our Raspberry Pi boards.
This protocol can be re-enabled by the raspi-config command, a command that allows us to alter the Raspbian configuration to our liking. But you have to know that disabling SSH is due to security and not by whim or error of the developers, something that must be taken into account when activating this protocol, because we may not need it and by activating it we endanger the security of SSH.
