Ubuntu 18.04.2 LTSにsnapdをインストールできない

自分のマシンのsnapdが機能せず、Sudo apt install --reinstall snapdを使用して再インストールしてみた

以下のエラーが発生しました。

Unpacking snapd (2.38+18.04) over (2.38+18.04) ...

私はマシンを再起動してこれを試しましたが、うまくいきませんでした。
どうすればこれを解決できますか？

更新：

  1. 出力に従って、コマンドsystemctl status snapd.serviceおよびjournalctl -xeを実行しました。以下はその出力です。
mithilesh@linux:~$ systemctl status snapd.service

  1. コメントに基づいて、以下は実行中のsnap list、snap versionおよびsnap warningsの出力です
mithilesh@linux:~$ snap list
error: cannot list snaps: cannot communicate with server: Get http://localhost/v2/snaps: dial unix /run/snapd.socket: connect: connection refused
mithilesh@linux:~$ snap version
snap    2.38+18.04
snapd   unavailable
series  -
mithilesh@linux:~$ snap warnings

  1. Sudo apt autocleanおよびSudo apt autoremoveを実行しても、エラーは発生しませんでした。ただし、Sudo apt updateの場合、google-chormeアプリケーションに対して警告が返されます。

出力は少し奇妙です。

snapdパッケージをパージして、以下のコマンドを使用して再インストールすることで、最初から始めることをお勧めします。

Sudo apt-get purge snapd
Sudo apt-get install snapd
