根据 apt 进程的输出，似乎您手动添加了一些其他非官方存储库，这没问题。但这样做时，您必须确保它们支持您的操作系统风格，或者至少存在 dists。您不能只是添加focal并希望它能正常工作。

当手动浏览到 时https://downloads.mariadb.com/MaxScale/2.4/ubuntu，没有名为 的 dist focal，这解释了404 Not Found错误。 也是如此http://ppa.launchpad.net/chris-lea/redis-server/ubuntu。

这个错误N: Ignoring file 'mariadb.list.old_1' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension本身就有点说明问题了，应该修复。你可以在这里阅读更多关于管理你的源和仓库列表的信息：存储库/Ubuntu
