How do i install lsphp80 or lsphp81 on Ubuntu 22.04.1?

hi, I'm running OLS on several ubuntu machines.
sometimes last year i installed lsphp80 on one of them.
I don't remember how i did it. I can't seem to find lsphp80 on the other machines, let alone 8.1.

I ran apt-get update and apt-get upgrade. if i try to install 80 or up the packages aren't found.
I only see up to 74 in sudo apt-cache search lsphp.
please advise
I tried that before and again now.
"LiteSpeed repository already setup!"
thank you for the reply. I'll contact support.

Edit: i think it might be related to the Ubuntu version. I tried to create a new machine from scratch. It's running Ubuntu 20.04.1 LTS, and i can see lsphp80, 81, and 82.
