小蛙有一台最早期的 VPS 已經不讓人重裝新版本作業系統,小蛙異想天開想直接從系統裡安裝升級,「事情絕對沒有憨蛙想得那麼簡單」,升級升到一半就哭了 …
升到一半狂噴錯,但已回不了頭,之後下 apt update
都會噴以下錯誤

根據這篇文章 GPG error: Release: The following signatures were invalid: BADSIG 的方法嘗試回復 apt-get
sudo apt-get clean
sudo mv /var/lib/apt/lists /tmp
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update
sudo apt-get clean
sudo mv /var/lib/apt/lists /tmp
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update
sudo apt-get clean sudo mv /var/lib/apt/lists /tmp sudo mkdir -p /var/lib/apt/lists/partial sudo apt-get clean sudo apt-get update
錯誤訊息變成這個

看起來好像是因為公鑰過期,查了該討論串裡的其他方法,發現下面這指令像是可以更新公鑰,死馬當活馬醫的心態試試看居然成功了!
apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
可喜可賀~!但 VPS 還是沒辦法升上去 >< (殘念),不過至少讓 apt-get 恢復正常了!
