删除ubuntu touch sdk完成的chroot

如何删除Ubuntu touch SDK所做的所有chroot ? 我在应用程序中找不到任何东西。
当我从终端进行mount ,我得到了这个:

 click-ubuntu-sdk-15.04-i386 on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb} type overlayfs (rw,lowerdir=/var/lib/schroot/union/underlay/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb},upperdir=/var/lib/schroot/union/overlay/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}) /proc on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/proc type none (rw,bind) /sys on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/sys type none (rw,bind) /dev on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/dev type none (rw,bind) /dev/pts on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/dev/pts type none (rw,bind) /home on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/home type none (rw,rbind) /tmp on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/tmp type none (rw,bind) /run/shm on /var/lib/schroot/mount/click-ubuntu-sdk-15.04-i386-ucca-1000-{32be949d-df4e-486b-a43e-9762cbe720eb}/run/shm type none (rw,bind) 

我怀疑我删除了

/etc/schroot/chroot.d/-ubuntu-sdk* / var / lib / schroot / chroots / -ubuntu-sdk *

重新启动和问题排序:)

谢谢Wayne 🙂
