Ubuntu 22.4 : KeyDb installation failed

I have Ubuntu 22.4 and want to install KeyDb.

But I receive “Unable to locate package keydb” after

$ echo “deb https://download.keydb.dev/open-source-dist $(lsb_release -sc) main” | sudo tee /etc/apt/sources.list.d/keydb.list $ sudo wget -O /etc/apt/trusted.gpg.d/keydb.gpg https://download.keydb.dev/open-source-dist/keyring.gpg $ sudo apt update $ sudo apt install keydb

What I do wrong? How to fix it?
