/etc/apt/sources.list 文件现在看起来不一样了，因为我做了一些事情
好的，所以在我发布这个问题之前，我试图非常彻底地遵循你们其中一人建议的另一篇帖子，这是对这个问题的预先存在的答案。
-其次，我检查了 ubuntu ppa 管理器（带有 gui 和复选框等），并且已选中 universe ppa 的复选框。我禁用了它，然后从这里重新启用了它，因为我害怕直接弄乱文件。另外，我不知道这是否相关，但我注意到我在设置区域中启用了反向移植。
-我认为这就是问题所在，这意味着我必须回滚我的更新或使用 kubuntu 的 backports ppa...？我是否可以手动启用 backports 以安装某些第三方软件的依赖项？
