Não é possível acessar o xfce4 do crouton de repente no acer chromebook 15

Question

Loading extra module: /usr/share/crosh/dev.d/50-crosh.sh
Welcome to crosh, the Chrome OS developer shell.

If you got here by mistake, don't panic!  Just close this tab and carry on.

Type 'help' for a list of commands.

If you want to customize the look/behavior, you can use the options page.
Load it by using the Ctrl+Shift+P keyboard shortcut.

Eu resolvi esse problema seguindo estas etapas do link .

Remova qualquer instalador existente da sua pasta Downloads. Buscar um instalador novo

Abra um shell crosh (Ctrl-Alt-T e digite shell)

Descobrir o nome do (s) seu (s) chroot (s).

Se você não sabe, sudo edit-chroot -a (em croutons recentes), ou sudo ls /usr/local/chroots irá lhe fornecer uma lista de nomes chroot. Execute uma atualização: sudo sh ~/Downloads/crouton -n chrootname -u , onde chrootname é o nome do seu chroot, certifique-se de que não haja erros. Reinicie: desligue completamente e reinicie. Tente iniciar seu chroot novamente.
