I was running apt-get dist-upgrade when my pi froze up. Afterwards, I booted it up and the keyboard and mouse went unresponsive. How do I fix this?
edit: By freeze I mean it locked up. I do not know why it froze. I did not overclock it and it did not overheat. The mouse and keyboard are plugged into a hub. The upgrades did not finish. It became totally unresponsive. Nothing happens when I plug and unplug them.
