Update Managerのオフラインエラー

Question

I3ウィンドウマネージャーを使用して、Ubuntu 14.04を実行しています。システムのソフトウェアとアップデートに問題があります。 update-managerを開始すると、次の画面が表示されます。

1_internet fail

これを見ると、インターネットは機能しています。プロキシを使用していません。

ok（右下）を選択した後、これが表示されます。

Ubuntu_base_update

画面を閉じるだけのinstall now（右下から）を選択します。次に、測定のためにSudo apt-get update; Sudo apt-get upgrade -yを実行し、コンピューターを再起動します。これは違いはありません。

Ubuntu Software

これらのラジオボタンを選択することはできません。少なくとも選択しても、選択されたままにはなりません。

左から（Ubuntu Software）これは私が持っているもので、これらのページにあるラジオボタンは選択できません：

Ubuntu Software

Other software

Updates

Authentication

Additional drivers

前のウィンドウで「閉じる」を選択した後、次のメッセージが表示される場合があります。

Information about available software

リロードを押すと、このエラーメッセージが表示されます（これも取得中にネットワークは正常です）

Fail to download repo

エラーメッセージテキストは次のとおりです。

W:GPG error: http://download.virtualbox.org trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 54422A4B98AB5139, W:Failed to fetch http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu/dists/trusty/main/binary-AMD64/Packages 404 Not Found , W:Failed to fetch http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found , E:Some index files failed to download. They have been ignored, or old ones used instead.

その画面を閉じた後、次を表示する更新マネージャーを取得します。

Update available

他の人がそうでなかったとき、これらがオプションである理由がわかりません。

これがapt-getなどとどのように結びついているのかわからないため、GUIの写真を表示しましたが、CLIメソッドを利用できることを嬉しく思います。

I3の代わりにUnityでログインしたため、アップデートマネージャーを使用していくつかのものをインストールでき、Universeパッケージのオプションを変更できました（i3では発生しなかったので、パスワードの入力を求められたため、権限が正しくありませんでした）。

ただし、Update Managerを（Unity内から）ロードすると、Check you internet connectionエラーが引き続き発生します。

更新マネージャーからのパッケージ情報をreloadしようとした後に得たエラーは次のとおりです。
