This section covers building Ubuntu 22.04/26.04 LTS compatibility layers on FreeBSD using debootstrap and WSL, along with Debian 13/Kali Linux build scripts.
Additionally, a Debian compatibility layer can be built using a similar method. For support status of other systems, see the /usr/local/share/debootstrap/scripts/ directory.
Start Building the Ubuntu Compatibility Layer (Based on Ubuntu 22.04 LTS)
Before building, you need to enable the relevant daemons and services:
Build the Ubuntu 22.04 LTS base system:
Specifying the Compatibility Layer Path
After building, you must mount the necessary file systems. Point the Linux compatibility layer default path to /compat/ubuntu to enable automatic mounting of the relevant file systems.
Take effect immediately:
Permanent setting:
Setting the Linux Kernel Version
You may need to set an appropriate Linux kernel version; otherwise, chroot will prompt FATAL: kernel too old.
7.0.11 is only an example; it is recommended to refer to the version numbers published on The Linux Kernel Archives.
Restart the Linux compatibility layer service:
Entering the Ubuntu Compatibility Layer
After completing file system mounting and kernel version settings, enter the Ubuntu compatibility layer to continue configuration.
chroot into the Ubuntu compatibility environment and remove software that may cause errors:
Switching Ubuntu Software Sources
Changing the software sources of the Ubuntu compatibility layer can improve download speeds.
After uninstalling rsyslog, you must change the software sources; since SSL certificates have not been updated yet, HTTPS sources cannot be used temporarily.
Use a text editor to edit the APT software source configuration file /compat/ubuntu/etc/apt/sources.list in the Ubuntu compatibility environment, and write the software sources:
Enter the Ubuntu compatibility layer, start updating the system, and install commonly used software:

Troubleshooting and Unfinished Items
What is the Command-line Launch Command for a Program?
Search in the following order (using gedit as an example):
Execute the package name directly: # gedit;
Use whereis package_name to locate it, then execute. whereis gedit;
Locate through the software icon: navigate to the /usr/share/applications directory, find the corresponding file by package name, and open it with a text editor (such as ee, nano) (the .desktop file is a text file, not a symlink or image), find the program launch command within it and copy it to the terminal to run.
Search globally using the find command (e.g., # find / -name gedit).
How to search for software?
Replace XXX with the name of the software you want to search for.
Missing .so Files
First check which .so files are missing; usually more than one is absent.
Based on the output libffmpeg.so => not found, determine that "libffmpeg.so" is missing.
Install the tool
Check which package the libffmpeg.so file belongs to:
Multiple packages provide this file; install any one of them.
Copy the file according to the above path and refresh the ldd cache:
Check the dynamic library dependencies of the executable /usr/bin/qq again:
# service linux enable # Enable the Linux compatibility layer service and set it to start on boot
# service linux start # Start the Linux compatibility layer service
# service dbus enable # Enable the D-Bus service and set it to start on boot (usually already configured by the desktop environment)
# service dbus start # Start the D-Bus service (usually already configured by the desktop environment)
# pkg install debootstrap # Install the debootstrap tool
# debootstrap jammy /compat/ubuntu http://mirrors.ustc.edu.cn/ubuntu/ # Use debootstrap to install Ubuntu Jammy into /compat/ubuntu
# echo "compat.linux.osrelease=7.0.11" >> /etc/sysctl.conf # Write the kernel version to the sysctl configuration file for permanent effect
# sysctl compat.linux.osrelease=7.0.11 # Set the kernel version immediately, usable in the current session
service linux restart
# chroot /compat/ubuntu /bin/bash # Enter the Linux compatibility environment
