incluso si también ejecutó el siguiente comando pero no tuvo suerte;
[email protected]:/# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7EA0A9C3F273FCD8
Executing: /tmp/apt-key-gpghome.rDOuMCVLF2/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 7EA0A9C3F273FCD8
gpg: keyserver receive failed: No keyserver available
Comprobar y averigüe cuánto tiempo tarda en arrancar su sistema Linux
La solución es Ejecutar esto para agregar la clave correcta:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"Fuente:https://docs.docker.com/install/linux/docker-ce/ubuntu/
si enfrenta un problema de error de Docker con Debian 11 Testing (bullseye):
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
Pero se puede resolver con:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /us
