后期还需要把ubuntu里的/dev/null设为777

运行x11软件

xhost +x250

xhost后面跟主机名

调试：

apt update报错

Now you can run '#chroot /compat/ubuntu22/ /bin/bash' Into Ubuntu

手动测试：

修改source.list文件，用https，然后执行：

chroot /compat/ubuntu22 /bin/bash -c "apt
remove rsyslog && apt update && apt upgrade "

还是报错

删掉，还是走mirror，

改成原始的

deb http://archive.ubuntu.com/ubuntu jammy main universe restricted multiverse
deb http://security.ubuntu.com/ubuntu/ jammy-security universe multiverse restri
cted main
deb http://archive.ubuntu.com/ubuntu jammy-backports universe multiverse restric
ted main
deb http://archive.ubuntu.com/ubuntu jammy-updates universe multiverse restricte
d main

不行，到ubuntu22里，把null设为777
