Newbie Ubuntu question

[frewind]

I think I already know the answer, but I want to confirm, and see what options I have...

I'm using the 0502 Ubuntu build from Pine64, based on longsleep's kernel.
I want to get kernel updates, because longsleep mentioned the addition of I2C (and as I've learned, I think I probably want his build instead of Pine64's).

Is there anyway to update my kernel without having to scrap what I have and reinstall?

This should sort you out...

As root run (sudo su -)

To update kernel

bash <(curl -s https://raw.githubusercontent.com/longsl..._kernel.sh)

To update uboot - you will probably need the updates

bash <(curl -s https://raw.githubusercontent.com/longsl...e_uboot.sh)
