Package gnome-control-center is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  gnome-control-center-data

E: Package 'gnome-control-center' has no installation candidate

失敗したsambaサーバーをインストールするまではすべてうまくいきましたが、理由はわかりませんが、このメッセージdpkg is lockedが表示されます。私はそれをアンインストールしてこれをSudo apt autoremoveしました。その後、再インストールを試みましたが、同じエラーが発生しますが、gnome-control-centerの代わりにsambaが表示されます。そのため、whereis sambaで示されているように、sambaのすべてのファイルを手動で削除しました。その後、このトラブルが始まりました。

更新：

Ubuntu 18.04 LTSを使用しています。

gnome-control-center パッケージはUbuntuの main リポジトリに存在します。これを有効にするには、以下の3つのコマンドのいずれかを実行します。

  • add-apt-repository with main：
    Sudo add-apt-repository main

  • add-apt-repository アーカイブの完全なアドレス：

    Sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main"

  • 編集 SourcesList with tee ：

    echo "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main" | Sudo tee -a /etc/apt/sources.list

有効にしたら、再度gnome-control-centerをインストールしてください。
