答案1
我注意到了这个错误：
Err:10 http://deb.debian.org/debian bullseye-security Release
404 Not Found [IP: 199.232.82.132 80]
也许是因为这个原因，您没有收到安全更新。
有一个目录名称明显改变
在 /etc/apt/sources.list 文件中，您需要使用新的目录名称。例如，将“/debian/”替换为“/debian-security/”。如果您不知道正确的名称，请打开旧存储库的 http 地址，您可能会找到正确的名称。
然后“sudo apt update && sudo apt upgrade”应用更改/更新。
