Manual install on Raspberry Pi

[myxxmikeyxx]

First I installed Raspberry pi OS Lite
Then I ran these comamnds:
sudo apt install software-properties-common sudo add-apt-repository -y ppa:teejee2008/timeshift sudo apt-get update sudo apt-get install timeshift

It installed fine but then after a reboot I tried to run
sudo apt-get update
And received this error
Err:6 http://ppa.launchpad.net/teejee2008/ppa/ubuntu kinetic Release 404 Not Found [IP: 185.125.190.52 80] Reading package lists... Done E: The repository 'http://ppa.launchpad.net/teejee2008/ppa/ubuntu kinetic Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.

Any Fix or should I just remove the repo since I have timeshift installed and it works?

Side note when using CLI you can use --tags O (stands for On-demand Backup). It just says that is an unknown tag
