该错误实际上并非来自 Linux Wine 的安装，而是由于安装过程中出现错误而导致的持续性问题。在这种情况下，它似乎来自未正确安装的 Microsoft 存储库。存储库“https://packages.microsoft.com/ubuntu/20.04/prod”似乎针对“lunar”版本进行了配置，但 Ubuntu 20.04 LTS（“Focal Fossa”）没有名为“lunar”的版本。基本上，您安装了错误版本的 Microsoft 存储库，因此您需要删除当前版本或将其更新为正确的版本。
您可以尝试以下方法：
sudo add-apt-repository --remove 'https://packages.microsoft.com/ubuntu/20.04/prod lunar'
删除不正确的存储库。然后，如果需要，请重新安装它。
