I am a newbie in Ubuntu. I am using a Windows XP machine (32 bit) OS and in that I installed VMPlayer and got iso image of Ubuntu 12.04 (downloaded from online). I started the Ubuntu and everything was fine. I heard where is issue with vi editor for that we need to update / install vim. First I tried sudo apt-get update, it was throwing many connection errors. Then somewhere i read to remove the vim-tiny and do a install of vim-full again. While doing I completely messed up with the VI. Now, even the old vi is not working. How to fix it?.
