更新 chromeos 后在 crouton 上运行 Ubuntu 时出现问题

我已经在 Toshiba Chromebook 2 上使用 Crouton 运行 Ubuntu 14.04 几个月了。今天我退出了 Crouton 并重新启动了我的 chromebook。重新启动并sudo startxfce4在 shell 中发出后，我收到以下错误

有谁知道出了什么问题吗？

答案1

解决了我自己的问题。下载了最新版本的 crouton 并发布sudo sh ~/Downloads/crouton -u -n chrootname，一切恢复正常。

这里chrootname指的是 chroot 的名称，可以在 chroot 创建期间选择性地指定（默认为发行版名称，但可以在 chroot 创建时使用该-n选项选择性地指定）。

答案2

我遇到了类似的错误，在 chrome 端自动更新后 xfce4 突然无法启动。通过下载最新版本的 crouton 解决了该问题（https://github.com/dnschneid/crouton）并运行sudo sh ~/Downloads/crouton -u -t xfce。 （-u用于更新并-t xfce指定 xfce 环境目标。）我绝不是专家，但它对我来说效果很好。
