I want to remove Black Arch Linux from my system because it's getting me some troubles at update time. I read in two different sources how to do it, but in the first step of both methods, the same trouble does not allow me to remove it.
First method start with
pacman -Sl | grep blackarch | cut -f 2 -d " " | xargs sudo pacman -Rn
Second method start with
paclist blackarch | cut -d' ' -f1 | xargs sudo pacman -R
... but at this point they both give me the same output
error: blackarch: signature from "Levon 'noptrix' Kayan (BlackArch Developer) <noptrix@nullsecurity.net>" is unknown trust
error: database 'blackarch' is not valid (invalid or corrupted database (PGP signature))
error: blackarch: signature from "Levon 'noptrix' Kayan (BlackArch Developer) <noptrix@nullsecurity.net>" is unknown trust
error: no targets specified (use -h for help)
The signature error and the database error are the same errors that I have when I try to update.
