docker.io: Hängt ab von: containerd (>= 1.2.6-0ubuntu1~)

Ich habe ein Problem bei der Installation von Docker in Ubuntu 20.04.

wolf@linux:~$ sudo apt install docker.io

wolf@linux:~$

Fehlermeldung besagt, dass ich brauchecontainerd (>= 1.2.6-0ubuntu1~)

Es ist seltsam, da ich bereits eine noch neuere Version habe, nämlich1.2.13-2

wolf@linux:~$ dpkg -l containerd.io 
Desired=Unknown/Install/Remove/Purge/Hold

+++-==============-============-============-======================================
ii  containerd.io  1.2.13-2     amd64        An open and reliable container runtime
wolf@linux:~$

Das System ist aktualisiert. Ich habe es bereits durchgeführt sudo apt update && sudo apt upgradeund es ist kein neues Update erforderlich.

Aktualisierung wie im Kommentar angefordert

wolf@linux:~$ lsb_release -a

Antwort1

containerdund containerd.iosind 2 verschiedene Pakete.

Versuchen Sie es dpkg -l containerd*und Sie sollten beide Pakete sehen.

$ dpkg -l containerd*

Wenn containerdes dort nicht vorhanden ist, fahren Sie mit der Installation mit fort sudo apt install containerd.

Lassen Sie mich wissen, ob das hilft.

Antwort2

Ich hatte den gleichen Fehler, aber eine komplexere Situation:

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

offensichtlich habe ich beim Update eine deutliche Warnung übersehen:

Use 'apt autoremove' to remove them.

Ich habe nicht tiefer gegraben, aber es gibt neuere Sicherheitspakete, die nicht zusammenpassen. Aber es erklärt nicht, warum die installierte Version docker.ionicht akzeptiert wird , die in Wirklichkeitcontainerd1.3.3-0ubuntu2.3>= 1.2.6-0ubuntu1~

Problemumgehung

Ich konnte dieses Problem beheben, indem ich ein Downgrade containerdauf das Hauptpoolpaket durchführte und dann Folgendes neu installierte docker.io:

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