Unity Ubuntu缺少启动器,许多权限问题和卸载问题

When I open Unity desktop on my Chromebook, the only thing I see is my desktop folders, no launcher or anything. This issue was described in another post (Unity doesn't load, no Launcher, no Dash appears), however, I went through this all and none of it has worked. To clarify ctrl+alt+t does not work. I am able to access sudo enter-chroot though. A little while ago, crosh said

Not unmounting /mnt/stateful_partition/crouton/chroots/precise as
another instance is using it.

after hitting ^C to exit the chroot because I had no other way to log off. this issue is described here (https://github.com/dnschneid/crouton/issues/1171). Nothing there worked for me either. After re-installing unity is now says this:

Unmounting /mnt/stateful_partition/crouton/chroots/xenial...
Sending SIGTERM to processes under /mnt/stateful_partition/crouton/chroots/xenial...

我已经尝试过重新启动,更新,升级等。

这是我启动和停止统一ubuntu的全部日志:
