有人能帮忙吗？
答案1
您连接到 apt 存储库的证书似乎已过期和/或不属于您或操作系统需要连接的版本。删除现有的 PPA，所以就您而言，
sudo add-apt-repository --remove ppa:cybermax-dexter/sdl2-backport
sudo add-apt-repository --remove ppa:webupd8team/java
然后更新
sudo apt-get update
然后尝试从 Kali 的存储库中找到您需要下载的确切资源。
如果您仍然需要添加存储库，请确认您尝试添加的存储库是否包含您要查找的包。在你的情况下，去这里并检查您的包是否在 Sources.gz 文件中可用。如果他们不这样做，你就走进了死胡同。 [也许是因为那里的最新源是仿生海狸（Ubuntu 18）的，他们理所当然地不再维护它。]
如果您仍然需要在 Kali 上使用 ubuntu 的二进制文件（嘿，linux 适合您，为了自由，请使用最新的存储库来做到这一点。）
