当我sudo apt upgrade在终端中运行时，收到以下消息：
E: Malformed entry 1 in list file /etc/apt/sources.list.d/vscode.list (URI)
E: The list of sources could not be read.
E: Malformed entry 1 in list file /etc/apt/sources.list.d/vscode.list (URI)
E: The list of sources could not be read.
当我这样做的时候 cat /etc/apt/sources.list.d/vscode.list
它打印这个
deb [arch=amd64,arm64,armhf signed-by=/etc/apt/trusted.gpg.d/packages.microsoft.gpg]
https://packages.microsoft.com/repos/code stable main
哪里有问题？
