我无法打开软件中心。当我尝试打开它时，窗口会打开几分钟然后关闭。当我尝试在终端中运行时，我收到此消息：

我尝试更新 ubuntu，希望它能解决问题，但似乎没有任何作用。 Steam 更新出现问题后，问题开始出现。我不知道这是否相关，但我收到的消息如下：
Steam needs to install these additional packages:
libgl1-mesa-dri:i386, libgl1-mesa-glx:i386

Reading package lists... Error!

我该如何解决？
答案1
看起来 steam 列表是空的或者已损坏，这会扰乱您的包裹更新。
我的第一次尝试是将所有 steam 列表移动/var/lib/apt/lists到我的主文件夹中的临时目录，并将 steam PPA 设置移动到/etc/apt/sources.d该目录。
然后再次执行apt-get update并查看缓存设置是否现在再次工作。如果是，则再次将 steam PPA 添加到 /etc/apt/sources.d 并再次执行apt-get update。如果您收到与上述相同的错误消息，则您可能需要更新您的 steam PPA。我希望当 apt 缓存不再出现任何故障时，软件中心会再次工作。
