Answer 1

没有适用于的软件包乌班图小鬼，将代号更改为hirsute：

sudo sed -i 's/impish/hirsute/' /etc/apt/sources.list.d/ookla_speedtest-cli.list
sudo apt update

Answer 2

我删除了 speedtest，但仍然留下了一个sources.list 文件，我将其删除，如下所示：

sudo apt remove speedtest-cli
sudo rm  /etc/apt/sources.list.d/ookla_speedtest-cli.list

经过多次挫折后，这解决了我的问题
