installing self hosted landscape, ppa:landscape/self-hosted-24.04 does not attach

"Connection timed out" can be caused by a temporary network problem. Have you tried again and do you repeatedly receive the same error?

I just tried what is in the install doc:

I copied the /etc/apt/sources.list.d/landscape-ubuntu-self-hosted-24_04-jammy.list from the lab/dev/test that we successfully installed.......and then ran "apt update" and got this error:

Am I needing a step to get gpg-keys to that repo?

Then I had a thought:

That seemed to work. It's now running the "DEBIAN_FRONTEND=noninteractive apt-get install -y landscape-server-quickstart"
