I installed 12.04 some week ago. After some operation, I changed the ownership of /etc directory and have some problems. That's why I decided to reinstall Ubuntu.
I downloaded CD distro, but my installation hangs at the "Copy the installation log" operation. I reboot my PC, load Live CD, delete all system disk partitions, try to reinstall but installation hangs again. Then, I download DVD distro and try to install from it, but "Copy the installation log" lasted for three hours and I have nest log of it:

What can I make for normal finishing installation of Ubuntu?
