[64 bit] 10.04 to 12.04 upgrade problem

view story

http://ubuntuforums.org – Hi, I have a 64 bit Ubuntu LTS 10.04 headless server that i just upgraded to 12.04. The upgrade did not seem super clean and there was a "failed to read on buffer copy for md5hash: Input/output error" when installing bash-completion. The server is running fine now but I am worried that it wont come back up after a reboot. Any commands that I can run to check whether the machine will come back up? How can I find out whether the install was clean? Many thanks in advance for the help (Hardware)
