找到解决方法：
apt-get --allow-releaseinfo-change update apt-get dist-upgrade
其实我们也可以更新源。
这两条命令都是在Debian系统中使用的包管理器 APT 的命令。其中：
apt-get --allow-releaseinfo-C++hange update：这条命令的作用是更新软件源信息，获取最新的软件包列表。其中的 "--allow-releaseinfo-change" 参数是允许在更新软件源信息时更改发行版信息，这通常用于解决软件包依赖关系的问题。
apt-get dist-upgrade：这条命令的作用是升级系统中所有已安装的软件包，包括那些因为依赖关系而不能自动升级的软件包。与 apt-get upgrade 命令不同，dist-upgrade 命令会自动处理依赖关系，确保所有软件包都能升级到最新版本。
