    Did you do something to your system just before this started to happen? If you strred your system with a root stick, playing whack-a-mole with the aftereffects isn't worth the effort.

This is the solution I came up with and tried, and it seemed to work, not sure why the perms changed on this file though :(:



sudo chmod 7755 /usr/lib/policykit-1/polkit-agent-helper-1


I also saw a version that tried: sudo chmod +s ... but I didn't like the file permissions, so I opted to mirror the other permissions for the files in /usr/lib/policykit-1/



See: https://chmodcommand.com/chmod-7755/

            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...
