У меня возникла проблема с установкой Docker в Ubuntu 20.04.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
docker.io : Depends: containerd (>= 1.2.6-0ubuntu1~)
E: Unable to correct problems, you have held broken packages.

Сообщение об ошибке говорит, что мне нужноcontainerd (>= 1.2.6-0ubuntu1~)
Это странно, так как у меня уже есть более новая версия, которая1.2.13-2
wolf@linux:~$ dpkg -l containerd.io

Система обновлена. Я уже выполнил sudo apt update && sudo apt upgrade
и новое обновление не требуется.
Обновление по запросу в комментарии
wolf@linux:~$ lsb_release -a
No LSB modules are available.

решение1
containerd
и containerd.io
представляют собой 2 разных пакета.
Попробуйте dpkg -l containerd*
, и вы увидите оба пакета.
$ dpkg -l containerd*

$
Если containerd
его там нет, установите его с помощью sudo apt install containerd
.
Позвольте мне знать, если это помогает.
решение2
У меня была та же ошибка, но ситуация была сложнее:
~# dpkg -l | grep containerd
ii containerd 1.3.3-0ubuntu2.3 amd64 daemon to control runC
~# apt-get install docker.io

Do you want to continue? [Y/n]
Я не копал глубже, но есть более новые пакеты по безопасности, которые не подходят друг другу. Но это не объясняет, почему docker.io
не принимает установленную containerd
версию 1.3.3-0ubuntu2.3
, которая на самом деле>= 1.2.6-0ubuntu1~

Обходной путь
Я мог бы решить эту проблему, перейдя containerd
на основной пакет пула и затем переустановив docker.io
:
~# apt-get install containerd=1.3.3-0ubuntu2
The following packages will be DOWNGRADED:
containerd
~# apt-get install docker.io
