I am currently trying to install debian 7.7 on a second hand computer, and I get a complete freeze during the install process, always at the same step - updating mirrors, 38%. Here is what I tried to find the cause :
- My ISO image is fine, I checked the SHA256
- I Burned it on a CD and on two different USB keys, same result
- I ran memtest+, the RAM looks fine
- I tried to run with a single RAM module (tested both), just in case memtest got it wrong, same result
- Just in case I waited two hours to see if the computer would unfreeze, it didn't
- I ran badblocks for 16 hours, the 1TB HDD looks fine
- I tried a 32bit install, same problem
My next move is to burn an installer from another distribution, just in case. Otherwise, I am stuck. Do you see anything else I could try to find the cause of the problem (and hopefully fix it) ?
28/11: I may have found the source of the problem.
The guy that gave me the computer told me he had troubles with the network - as DHCP worked, I assumed the problem was somehow related to his windows install. But a try at installing linux mint from the graphical installer gave me a hint : the installer stalled when downloading content.
It looks like the network interface is damaged - it works enough to run a DHCP request, but as soon as you start transferring content, it crashes. Right now the computer is in the hands of its new owner. I disabled the onboard ethernet controller and told him to buy a network card. He will tell me if it worked soon.
