El mensaje de error dice que necesitocontainerd (>= 1.2.6-0ubuntu1~)

Es extraño porque ya tengo una versión aún más nueva, que es1.2.13-2

wolf@linux:~$

El sistema está actualizado. Ya lo realicé sudo apt update && sudo apt upgradey no se requiere una nueva actualización.

Actualizar según lo solicitado en el comentario.

wolf@linux:~$ lsb_release -a

containerdy containerd.ioson 2 paquetes diferentes.

Pruébelo dpkg -l containerd*y debería ver ambos paquetes.

$ dpkg -l containerd*

rc  containerd.io  1.2.13-2       amd64        An open and reliable container runtime
$

Si containerdno está ahí, continúa e instálalo con sudo apt install containerd.

Déjeme saber si esto ayuda.

Tuve el mismo error pero una situación más compleja:

~# dpkg -l | grep containerd
ii  containerd                            1.3.3-0ubuntu2.3                  amd64        daemon to control runC

Obviamente, pasé por alto una advertencia clara al actualizar:

No profundicé más, pero hay paquetes de seguridad más nuevos que no encajan. Pero no explica por qué docker.iono acepta la containerdversión instalada 1.3.3-0ubuntu2.3que de hecho es>= 1.2.6-0ubuntu1~

Solución alterna

Podría solucionar este problema bajando containerdal paquete del grupo principal y luego reinstalando docker.io:

~# apt-get install containerd=1.3.3-0ubuntu2
The following packages will be DOWNGRADED:
  containerd
~# apt-get install docker.io
