我进入 Ubuntu 软件，搜索playonlinux然后单击remove：
它这样做...
然后仍然显示已安装。重启后也等待了 10 个小时。
我能做些什么？
Canonical 是否计划在 2018/2019 年提供正常运行的软件安装/卸载实用程序？有人知道他们的路线图中是否有类似的东西吗？我可以在某处看到路线图吗？
更新：
当执行时sudo apt remove playonlinux，会发生以下事情：

好的。这是根据您的输出进行的尝试。在开始运行时，
sudo apt autoremove
这通常会删除所有不再需要的过时软件包。接下来，看起来，您正在使用未签名的内核。您应该选择使用 LTS 内核。最新的 LTS 内核是 4.19。（请参阅这里版本）。如果你想知道如何安装/升级 Linux 内核，你可以查看这。但是，建议坚持使用您正在使用的 Ubuntu 版本或 LTS 版本附带的默认内核。接下来，正如提示所暗示的那样，PlayonLinux 未安装。当您从软件中心卸载它时，它可能已被删除。
注意：Synaptic 软件包管理器也是一款出色的工具，可以帮您解决所面临的问题。它可以帮助您安装升级、修复依赖性问题等等。请参阅这里。
