Okay, here is the definitive answer on how to solve this problem.
First, let me recommend using nano (a text editor) instead on vi. VI makes complete sense for those who have used before but it just wastes everyone's time trying to explain how to use it.
Here are the steps to take:
1. cntrl+2 will get you to another virtual console. You will see a $ (standard user) prompt. You need to have root access in order to edit the file and save it.
2. $sudo -i The prompt will now change to a # meaning you have root access
3. #nano /usr/bin/lite-installer.sh You will now be in the nano editor editing the file.
4. Here's the 'tricky' part. this script has functions listed at the top so if you scan for formatPartitions, you will find it towards to top of the file. HOWEVER, search again almost at the end of the file and you'll see a list of commands. One of those is formatPartitions. (It appears on it's own line) THAT is the line you must comment out by placing a # in front of it.
5. place a # sign in front of that formatPartitions command. So that it looks like this
6. save the file using ctrl+o (WriteOut) and exit the nano application (Now you should be back at the # command prompt.)
7. type in #/usr/bin/lite-installer.sh (the installer will rerun and it won't get hung up this time)
DEVELOPER QUESTION: Can we get this fixed? I have no idea why this is happening, but it's causing quite a few headaches for some of us.
