答案1
嗯，startkde 位于/usr/local/bin/startkdechroot ( /usr/local/chroots/CHROOTNAME/usr/local/bin/startkde) 但 crouton 启动脚本尝试运行/usr/bin/startkde。
这就可以解释/bin/sh: 0: Can't open /usr/bin/startkde
尝试这个：sudo enter-chroot -t kde xinit /usr/local/bin/startkde
如果可行，则问题出在启动脚本上。要永久修复此问题，请sudo sed -i 's/\/usr\/bin\/startkde/\/usr\/local\/bin\/startkde/g' /usr/local/bin/startkde从 chroot 外部运行。
