更新一下apt套件庫清單:
apt-get update

請執行以下動作解決之:
apt-get install debian-keyring debian-archive-keyring
apt-key update
如果出現被鎖住的狀況:
E: 無法將 /var/lib/apt/lists/lock 鎖定 - open (11: 資源暫時無法取得)
E: Unable to lock directory /var/lib/apt/lists/
則刪掉lock檔即可
rm /var/lib/apt/lists/lock
升級一下系統
apt-get upgrade
安裝rsync(方便日後備份)、htop(方便觀察主機狀況)、 fping(設定排程時可能會用到)、 sshfs及nfs(方便遠端掛載備份,無此需求可免裝)、zip(以壓縮)、unzip(以解壓縮)、NTP (校時工具)、安裝ca-certificates,避免wget無法下載https檔但,以及https網址時,Google快速登入會出現錯誤訊息(Google_IOException: HTTP Error: (0) error setting certificate verify locations: CAfile: /etc/ssl/certs/ca-certificates.crt CApath: /etc/ssl/certs)
apt-get install rsync htop fping sshfs nfs-common zip unzip ntp ntpdate ca-certificates wget
