If the above link does not work, use the below command to download latest release, as of 2022

latest is 2.1.1, can go to release to check if newer releases are out:

(I.E if it gives cmd not found error) :

(2.24.0 is latest as of jan 17 2024)

sudo curl -L "https://github.com/docker/compose/releases/download/v2.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

continune .......

docker compose executable will be located in /usr/local/bin/docker-compose

but it need to haver docker group permission to be executable :

https://stackoverflow.com/questions/59265190/permission-denied-in-docker-compose-on-linux

sudo chmod +x /usr/local/bin/docker-compose
---------------------------------------------------------
to run docker-compose without sudo 
In addition to the comments provided in the question
sudo usermod -aG docker $USER                  # to add myself to docker group 
(this step should already been done
 if u wana to run docker without sudo in docker installation guide above)


sudo chgrp docker /usr/local/bin/docker-compose     # to give docker-compose to docker group,
sudo chmod 750 /usr/local/bin/docker-compose   # to allow docker group users to execute it

to test  run docker-compose --version
