I have a time-consuming program running in Lubuntu 18.04 Live. It will take around one day to finish. After the program finishes the computer shuts down.
But since I am running Lubuntu Live, the computer asks me to
Please remove the installation medium then press enter
after initiating the shutdown. I will be traveling away before the program can finish and will not be back in a few weeks. I don't want the computer to be powered on all that time.
My question is: Is there a timeout after which the computer will eventually shut down, or is there any way to skip this prompt and completely shut down Lubuntu Live?
