Instalei o kubuntu 22.04 novo em meu laptop e quando tento instalar o docker, instalei docker-ce e docker-compose :

Description: Docker: the open-source application container engine
Docker is a product for you to build, ship and run any application as a
lightweight container
.
Docker containers are both hardware-agnostic and platform-agnostic. This means
they can run anywhere, from your laptop to the largest cloud compute instance and
everything in between - and they don't require you to use a particular
language, framework or packaging system. That makes them great building blocks
for deploying and scaling web apps, databases, and backend services without
depending on a particular stack or provider.

Eu executei o comando:

sudo chmod +x /usr/bin/docker-compose

sem erros.
Mas executando o docker no meu projeto, recebi o erro "Permissão negada" de qualquer maneira

serge@serge-at-home:/_wwwroot/lar/FilamentBanners/__DOCKER$ docker-compose up -d --build

também executo comandos:

usermod -aG docker $USER

e

newgrp - docke

Mas mesmo assim o mesmo erro... O que perdi durante a instalação?

    Você está executando o antigo Docker Compose ( docker-compose), que não é mais desenvolvido (e também não está mais incluído nos repositórios do Docker).

    Eu recomendaria mudar para o novo plugin Docker Compose V2 ( docker compose), em vez de solucionar problemas de software não suportado.

    Primeiro remova o pacote antigo: (dos repositórios do Ubuntu, não correspondendo à sua versão do Docker)

    sudo apt-get remove docker-compose

    Agora instale a nova versão: (dos repositórios Docker)

    sudo apt-get install docker-compose-plugin

    De agora em diante, em vez de usar docker-compose, use docker compose- veja também aqui para criar um alias.
