I had two computers running fedora 14 and finally decided to upgrade. Opted for 16 rather than 17. First one is a 64 bit desktop, no problems. I used a "preupgrade" procedure described at an internet site.
So I started the same procedure on my laptop (also 64 bit), but after starting realized I didn't have the power supply and it was on battery. I let it finish the first step, to where it wanted to reboot. Now I was low on battery, so just shut it down. After plugging it in, however, it wouldn't respond at all--like a crash on hibernating, although I had shut it down normally (I thought). Had to remove the battery to get to start, but when i restarted I went right to fedora 14; which seemed normal; rather than going into the upgrade.
I tried rerunning preupgrade, and got an error message.
Any thoughts on how to restart the upgrade? should I login at a lower runlevel as root?
thanks for any suggestions.
