I installed Raspbian Jessie Lite on an R Pi 1 B a few weeks ago. It's been running fine. Today I decided I should check for updates, so I typed the usual:
$ sudo apt-get update
$ sudo apt-get upgrade
That was about 2 hours ago and it's still updating! It's not frozen. The information is still scrolling. Did I just go full Jessie on this thing!? If so, is there a way to revert (without reinstall)? Also, is there a way to keep this from happening again? (Do I need to do --no-install-recommends?)
