ppa repository does not have a release file

I added the ppa repository with sudo add-apt-repository ppa:thopiekar/sierrabreeze, but whenever I do sudo apt update, I am greeted with this. The sierrabreeze package is unable to be located.

I am running Debian 10 64-bit with Plasma 5.14.5 and Linux 4.19.0-6-amd64

In debian, the solution is execute: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D51DB14E9FFECCF3 to update key with PPA

Have the same problem, tried @luismorenomx 's solution but end up in the same place, also when doing
sudo add-apt-repository ppa:thopiekar/sierrabreeze
The last line of gpg says: no valid OpenPGP data found

This worked for me on Ubuntu 24.04

sudo add-apt-repository -r ppa:thopiekar/sierrabreeze
sudo add-apt-repository "deb https://ppa.launchpadcontent.net/thopiekar/sierrabreeze/ubuntu jammy main"
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D51DB14E9FFECCF3
sudo apt-get update
sudo apt install sierrabreeze
