I tried making new threads on the issue but nobody seems to reply.
Stayed up all night to get this resolved.
Maybe it make more sense posting here...

My question is:

Someone said that I have to uninstall power kernel first if I use the OTC update to PR1.2.

So I don't have to do that if I use NSU?

What about the disclaimer of power kernel that says that NSU "become broken"?

So now I'm trying to uninstall the overclocked power kernel so I could update to PR1.2 OTC.

And I'm following the deinstallation instructions here

But when I enter the command apt-get install --reinstall -y kernel kernel-flasher

I get this error: E: You don't have enough free space in /var/cache/apt/archives/

I tryed uninstalling a bunch of apps to free up room but still no luck

Please someone help me. This is very frustrating.
