我的 MBR 被感染后，我刚刚第一次下载了 Ubuntu。我进入 Ubuntu 软件中心并尝试搜索“Skype”，它无限加载，除了“全部”部分之外的所有内容都无限加载，我该如何解决这个问题？当我按下一个类别时，它只显示三个矩形中的点？
我还尝试通过终端启动 USC，它成功了，但它似乎是旧版本。当我通过终端启动它时，我得到了这个：

答案1
Skype 应该能够直接从 Ubuntu 使用的存储库安装。
检查 Skype 的来源，它似乎来自Partner存储库。因此需要启用这些。
由于我已经安装了它，所以我运行apt-cache去获取它来自的存储库。
~$ apt-cache showpkg skype
Package: skype
Versions:
4.3.0.37-0ubuntu0.12.04.1 (/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_xenial_partner_binary-amd64_Packages) (/var/lib/dpkg/status)
正如您所见，合作伙伴是名称的一部分。
转到设置->软件和更新->其他软件选项卡。
选择合作伙伴框后（即我列表中的前 2 个），单击“关闭”，然后它会重新加载缓存。
如果不存在，请单击添加，然后添加以下两行（逐一添加）：
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
当你关闭它时，它应该更新缓存。
现在，您应该能够从命令行安装 Skype：
sudo apt install skype
希望这可以帮助！

我昨天安装了 Xubuntu，也是这样。更新并重启解决了问题。
更新：
sudo apt-get update
sudo apt-get dist-upgrade
