What is the problem?
I was installing an update with this command (sudo apt-get update && sudo apt-get upgrade --yes) in my terminal. while it was updating it crashed. i can't even get in my OctoPrint with ssh and http://octopi.local/ also does not work. I was updating it because I installed a plugin for a screen on my raspberry pi and they told mee to update.
What did you already try to solve it?
i unplugged my raspberry pi and tried to restart it that way. I also took an other sd card with octopi installed.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, what kind of hardware precisely, ...)
I am use a raspberry pi B+.
