In this command, after install caddy server in Ubuntu 22.04 system, I can't caddy binary file in bin folder. I think there are some issues in installing, I can't find what is error.

I have this error 2023-05-07 02:26:31,842 INFO spawnerr: can't find command '/usr/local/bin/caddy'

I have installed with this way
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/testing/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-testing-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/testing/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-testing.list sudo apt update
sudo apt install caddy

How can I install caddy server in Ubuntu system correctly. please help me
