我在 Ubuntu 17.10 的应用程序概述中看到一个名为“浏览”的程序。
这个应用程序是做什么的？它是 Ubuntu 17.10 的默认应用程序吗？
单击启动器没有任何反应。
附加信息
我相信它的启动器是/usr/share/applications/org.laptop.WebActivity.activity.desktop。
如果我尝试在命令行上Exec=从.desktop文件运行命令，我会收到以下错误：
cd /usr/share/sugar/activities/Browse.activity

答案1
我正在使用 Impish 21.10，但仍然有这个问题。
经过许多年和许多版本的发布后，我找到了答案......
“浏览”应用程序
“浏览”应用程序的目的是允许 Gimp 显示帮助信息。
解释
当我安装的时候gimp，我也会安装gimp-help-en。
软件包
gimp-help-en需要软件包gimp-helpbrowser。（请参阅gimp-帮助-en）。但是
gimp-helpbrowser在 Ubuntu 17.10 及更高版本中不可用，因此满足此依赖关系的替代包是www-browser。www-browser是一个虚拟包，有 19 个包提供www 浏览器。该计划
sugar-browse-activity是这 19 个计划之一。请参阅糖浏览活动。（在我的例子中，apt选择安装sugar-browse-activity而不是其他 19 个应用程序之一，例如firefox，因为我安装了firefoxdeb 包后安装gimp-help-en）。
因此，sugar-browse-activity负责安装文件，/usr/share/applications/org.laptop.WebActivity.activity.desktop该文件应该启动“浏览器”应用程序。（查看文件列表）。
解决
我在 Ubuntu 21.10 中测试了 Gimp 2.10.24，但这可能也适用于其他版本的 Ubuntu。
使用帮助只会启动我的默认浏览器（Firefox）并在网络浏览器中显示内容。
www-browser因此，请避免安装“浏览”应用程序，在安装之前安装提供的 19 个软件包之一 gimp-help-en。请参阅糖浏览活动。 注意火狐被列为这些应用程序之一。
Ubuntu 21.10
在 Ubuntu 21.10 中，wslu（对于Windows 10 Linux 子系统）是另一个提供www-browser（参见Impish 的 sugar-browse-activity）。
因此，如果您尝试安装，则有可能您会wslu在 Ubuntu 21.10 系统上安装gimp-help-en。
再次强调，避免安装或“浏览”应用程序的解决方案是在安装之前wslu安装 Impish 中提供的 24 个软件包之一 。请参阅www-browsergimp-help-en糖浏览活动。 注意火狐被列为这些应用程序之一。
