dpkg --configure -a update-initramfsでスタック
今日、私はSudo apt upgradeを試みましたが、次のエラーが発生しました：E: dpkg was interrupted, you must manually run 'Sudo dpkg --configure -a' to correct the problem.。
ただし、dpkg --configure -a（ルートとして）を実行すると、update-initramfs: Generating /boot/initrd.img-4.4.6-3-surfaceで数時間スタックします。
私はMS Surface Pro 3でUbuntu 16.04を実行しています（Windows 10でのデュアルブートですが、これまでに問題が発生したことはありません）。
また、GUIを使用してコンピューターの電源をオフにしようとすると、シャットダウン画面でハングし、手動で電源をオフにする必要があることに気付きました。その問題は最初の問題と関係があるのでしょうか？
Sudo strace dpkg --configure -aの出力は次のとおりです（開始と終了のみを含めました）。
