Ubuntu 20.04 に docker をインストールする際に問題が発生しています。

wolf@linux:~$

エラーメッセージには、containerd (>= 1.2.6-0ubuntu1~)

奇妙なことに、私はすでにさらに新しいバージョンを持っていますが、1.2.13-2

wolf@linux:~$ dpkg -l containerd.io

wolf@linux:~$

システムが更新されました。すでに実行済みなのでsudo apt update && sudo apt upgrade、新たな更新は必要ありません。

コメントでリクエストされたとおり更新

答え1

containerd2 つの異なるパッケージですcontainerd.io。

試してみるdpkg -l containerd*と、両方のパッケージが表示されるはずです。

$ dpkg -l containerd*
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

ii  containerd     1.3.3-0ubuntu2 amd64        daemon to control runC
rc  containerd.io  1.2.13-2       amd64        An open and reliable container runtime
$

ない場合はcontainerd、 でインストールしてくださいsudo apt install containerd。

これが役に立つかどうか教えてください。

答え2

私も同じエラーを経験しましたが、状況はより複雑でした。

~# dpkg -l | grep containerd

明らかに、私は更新中に明確な警告を見落としていました:

詳しくは調べませんでしたが、セキュリティに関する新しいパッケージがあり、それらは互いに適合しません。しかし、実際にはインストールされているバージョンdocker.ioを受け入れない理由は説明されていません。containerd1.3.3-0ubuntu2.3>= 1.2.6-0ubuntu1~

回避策

containerdメイン プール パッケージにダウングレードしてから再インストールすることで、この問題を解決できましたdocker.io。

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