This repository contains a helper script for updating Debian within an LXC (Linux Containers) environment. The script usrmerge-lxc-fix.sh is designed to fix a specific error related to the usrmerge package that occurs when updating to Debian Bookworm.
The usrmerge package in Debian is designed to streamline the system's directory structure by merging directories like /bin, /sbin, /lib* into /usr. This structure is common in several other Linux distributions. However, in an LXC container environment, this can cause problems due to the way LXC handles directories and filesystems using bind mounts.
The error message usually seen is "FATAL ERROR: /lib/modules/ is a mount point." This is due to the usrmerge package interpreting the mount point as a sign that the system is using User Mode Linux (UML), a different type of Linux virtualization. This leads to the failure of the package configuration.
To solve this issue, I've developed a script called usrmerge-lxc-fix.sh which is provided in this repository. The script modifies the convert-usrmerge file by inserting an exit; command at the 4th line to bypass the process that checks for mount points, which leads to the error.
After running the script, you can proceed with your Debian Bookworm update as usual. Once the update is completed, the script will prompt you to undo the changes made to the convert-usrmerge file. This ensures that your system will not have residual modifications from this temporary fix.
- Download the
usrmerge-lxc-fix.shscript from this repository. - Run the script in your LXC Debian container before proceeding with the update to Debian Bookworm.
git clone https://github.com/jordanhillis/usrmerge-lxc-fix.git
cd usrmerge-lxc-fix
chmod +x usrmerge-lxc-fix.sh
./usrmerge-lxc-fix.sh

While this script has been created to address this specific issue, system updates can sometimes present unexpected challenges. If you encounter other issues or need further assistance, I recommend seeking advice from knowledgeable communities or professionals who have a deep understanding of Debian and LXC environments.
