vmlinuz-4.18.12-041812-generic has invalid signature

I upgraded my kernel today with ukuu, and since then I cant boot because i'm getting this errors: 



error: /boot/vmlinuz-4.18.12-041812-generic has invalid signature

error: you need to load the kernel first


I have dual boot with windows 10 and ubuntu 18.10 (Upgraded today)



Update: I managed to boot to older kernel that i chose from "Advanced
options for Ubuntu" in grub



But I need to upgrade my kernel and if I do that I still get the same problem...






dual-boot kernel

          Is this a new Fibonacci Identity?

          Image
          6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
