I was trying to change the ownership on an external drive, and mistakenly used
sudo chown -RL myuser:myuser /media/"New Volume"
Unfortunately, it changed the ownership on the entire drive to myuser. I've since changed the ownership back to root on everything except the /home/myuser directory. But, I still have problems, such as google-chrome didn't work anymore, I can't see mounted drives, and pulseaudio doesn't work. (There are probably more--but these were enough to make me want to fix this).
I downloaded the Ubuntu 12.04 LTS DVD (x86_64) and am booted into it right now. When I try to do the installation, I don't have an option to "Upgrade from 12.04 to 12.04" (Possibly this is due to the fact that I have two partitions:
- Ubuntu 12.04
- Linux From Scratch
So my questions are these:
- How do I do an upgrade (if possible)?
- If I have to reinstall, and choose not to format the partition that my / is on (which includes /home, /bin, /usr, /etc, and so on), what will I lose (It says that it will delete everything in /etc /usr /bin ....)?
