大家好，Ubuntu 社区，
今天，当我尝试从终端更新时，我收到了上述标题的警告。不确定是否可以继续，但这是终端的完整更新输出。yay只是sudo apt update && sudo apt list --upgradable && sudo apt upgrade && flatpak updatebtw 的别名：
scott@ubuntu:~$ yay

正如您在上面的命令中看到的，我确实有两个用于 Vivaldi 网络浏览器和 Papirus 图标主题的 PPA，如果相关的话，它们都来自其官方源代码创建者。不确定直接更新是否可以或安全，但我是否应该在开始时按 Y 并接受更新，或者我是否需要进行任何手动干预？
当然感谢任何帮助，谢谢。
