我想升级我的系统，但是面临这些问题：
- 每当我按下软件更新程序时都没有任何反应，有时我会收到错误报告。
sudo apt update给了我这个：Reading state information... Done 1363 packages can be upgraded. Run 'apt list --upgradable' to see them.

然后cat /etc/apt/sources.list给我这个：

看起来你的 sources.list 可能相当混乱。我怀疑你至少有一个 ppa 配置错误，这导致 apt 无法从正确的位置下载源。
我建议你从以下网址下载默认的 ources.list 文件这里。接下来，找到您的 sources.list 文件；通常它位于/etc/apt/sources.list。我建议您将当前文件重命名为 sources.list.bak 之类的名称，然后尝试使用默认 sources.list 运行 apt，如下所示。
mv sources.list sources.list.bak
cp path/to/downloaded/sources.list sources.list
sudo apt update
sudo apt upgrade
默认的 sources.list 无法访问您从自定义 ppa 安装的任何软件，但它应该允许您更新工具链中必要的内容，然后允许您升级。由于您正在升级，因此无论如何都需要再次添加这些 ppa。祝你好运！

此问题几乎与您尝试下载的服务器的连接性有关。请检查与服务器的连接性或更改存储库链接，然后在此处分享结果。
