我有 Ubuntu 版本 20.04.2 LTS 焦点。

Answer 1

这是 this solution 的简单概括但是因为我不能发表评论，所以我正在发帖以防这种概括对其他人有所帮助。
似乎可行的方法是添加存储库。E: The repository 'http://ppa.launchpad.net/<org>/<repo>/ubuntu focal Release' does not have a Release file.解决方案:sudo apt-add-repository -r ppa:<org>/<repo> 示例
所以在我的情况下，以下工作sudo apt-add-repository -r ppa:kasra-mp/ubuntu-indicator-weather
