Answer 1

Albert 是我最喜欢的快速启动器，所以我将它安装在 Ubuntu 18.04 中。您遇到的错误似乎反映了 PPA 的临时或永久问题。

通过 PPA 安装

Albert的User guide参考了openSUSE 网站的更多说明。在那里，您单击 Ubuntu 图标。您会在那里找到连接到与您尝试的 PPA 不同的 PPA 的说明。

通过 .deb 安装文件安装

我更喜欢通过下载 .deb 安装文件来安装 Albert。优点是您不需要添加外部 PPA。缺点是程序不会在新版本出现时自动更新。根据您的看法，这实际上可能是一个优势。Albert 正在大力发展，新版本有时可能会出现问题。

页面上的第二个链接“直接抓取二进制包”允许您下载 64 位或 32 位 .deb 安装文件。右键单击下载的 .deb 并选择“使用软件安装程序打开”。这将使用 Ubuntu 软件安装 .deb 文件。
