回覆至：MP520-20：Debian Trixie 改變 APT Key 管理政策

[Huang Jia-Bin]

真糟糕，RSA1024 不能用了。請改用 RSA3072 的 mp520v2.gpg，並且把MP520的apt sources結構改變如下，以符合未來Debian的policy：

一、下載 mp520v2.gpg

$ sudo wget -O /usr/share/keyrings/mp520v2.gpg http://deb.mapleboard.org/mp520v2/mp520v2.gpg

二、下載 Sources

$ sudo wget -O /etc/apt/sources.list.d/debian.sources  http://deb.mapleboard.org/mp520v2/debian.sources

$ sudo wget -O /etc/apt/sources.list.d/mp520v2.sources  http://deb.mapleboard.org/mp520v2/mp520v2.sources

$ sudo wget -O /etc/apt/sources.list.d/vscode.sources  http://deb.mapleboard.org/mp520v2/vscode.sources

三、刪除老的 sources.list

$ sudo rm /etc/apt/sources.list

$ sudo rm /etc/apt/sources.list.d/mp520.list

$ sudo rm /etc/apt/sources.list.d/vscode.list

四、大功告成

$ sudo apt update

$ sudo apt upgrade
