Identifying XanMod packages is the foundational step in completely removing the custom kernel. This process ensures that all associated files and modules are targeted for removal, preventing residual conflicts or system instability. Proper identification streamlines the subsequent removal steps, contributing to a clean and stable system.
-
Package Naming Conventions
XanMod packages typically include “xanmod” in their name, making them identifiable through package manager tools. This naming convention simplifies the search process, enabling administrators to quickly list installed packages containing the keyword. For example, the kernel image package might be named `linux-image-xanmod`. Identifying these conventions is crucial to ensure no related packages are overlooked during the removal process. Misidentification may lead to incomplete removal and potential system errors.
-
Utilizing Package Manager Tools
Package managers like `dpkg` (Debian/Ubuntu) or `rpm` (Red Hat/Fedora) provide command-line utilities to list installed packages. Using commands such as `dpkg –list | grep xanmod` or `rpm -qa | grep xanmod` allows users to display all packages containing the term “xanmod”. These tools are essential for accurately identifying all components of the XanMod kernel. These tools will find all installed packages that contain xanmod
-
Checking for Dependencies
XanMod packages may have dependencies on other software components. Identifying these dependencies is critical to avoid inadvertently removing essential system packages. Package managers often provide features to list dependencies, ensuring that only XanMod-related components are targeted for removal. Ignoring this step can lead to unintended consequences, such as breaking core system functionality. These tools provide essential dependecies which should be considered.
-
Verifying Package Integrity
Before initiating removal, verifying the integrity of identified XanMod packages ensures that the packages are valid and haven’t been corrupted. Package managers provide mechanisms for checking package checksums or signatures, confirming their authenticity. This verification step minimizes the risk of encountering errors during the removal process. Corruption during removal can cause huge problems.
The successful identification of XanMod packages is integral to a complete and safe removal process.

Removal of packages associated with XanMod is a critical stage in the process of completely removing the custom kernel. This phase ensures that the system is free from residual components, preventing potential conflicts with the default kernel or future installations. Improper removal can lead to system instability, boot failures, or unexpected behavior.
-
Using Package Manager Commands
Package managers, such as `apt` on Debian-based systems or `dnf` on Fedora, provide commands to remove software packages. The `apt remove` or `dnf remove` command, followed by the specific XanMod package names identified in the previous step, initiates the removal process. For example, `sudo apt remove linux-image-xanmod-generic` would remove the XanMod kernel image. Executing these commands with elevated privileges ensures that the system can properly modify the installed packages.
-
Handling Dependencies During Removal
Package managers automatically handle dependencies during removal. When a XanMod package is removed, the package manager identifies and removes any dependent packages that are no longer required. This process avoids leaving orphaned packages on the system, contributing to a cleaner removal. However, it’s crucial to review the list of packages being removed to ensure that no essential system components are inadvertently targeted.
-
Purging Configuration Files
Some packages leave configuration files behind after removal. To completely remove all traces of XanMod, the `purge` option can be used with some package managers. For example, `sudo apt purge linux-image-xanmod-generic` will remove the package and its associated configuration files. This step ensures that no residual settings interfere with the default kernel or future kernel installations. However, caution should be exercised when purging configuration files, as it may remove customized settings that were not specific to XanMod.
-
Addressing Kernel Modules
XanMod may install custom kernel modules. These modules must also be removed to complete the process. Typically, the removal of the kernel image package will also remove these modules. However, it’s prudent to verify that all related modules have been removed by checking the modules directory or using the `lsmod` command to list loaded modules. Remove modules using `rmmod `.
The comprehensive removal of XanMod-related packages, along with their dependencies and configuration files, is essential for a clean and stable system.

3. Update bootloader config
After removing XanMod packages, the bootloader configuration must be updated to ensure the system boots into the intended kernel, typically the distribution’s default. This step is crucial for successfully completing the kernel removal process and preventing boot failures.
-
Bootloader’s Role in Kernel Selection
The bootloader, such as GRUB (Grand Unified Bootloader), is responsible for loading the operating system kernel during system startup. It reads a configuration file to determine which kernel to load and presents a menu to the user if multiple options are available. Without updating this configuration after removing XanMod, the system may still attempt to boot into the uninstalled kernel, leading to a non-functional system. A misconfigured bootloader directly inhibits proper system startup.
-
Generating a New Configuration File
Tools like `update-grub` on Debian/Ubuntu-based systems or `grub2-mkconfig` on Fedora generate a new bootloader configuration file based on the currently installed kernels. These tools scan the system for available kernels and create a configuration file that lists them in the boot menu. Running this command after removing XanMod ensures that the configuration file reflects the change and that the default kernel is properly selected. Incomplete configuration generation will mean the old config files is still in function
-
Setting the Default Kernel
The bootloader configuration file specifies the default kernel to load when no user intervention occurs. After removing XanMod, it’s essential to verify that the default kernel is set to the distribution’s standard kernel. This can be achieved by manually editing the bootloader configuration file or by using bootloader configuration tools. Failure to set the correct default kernel will result in the system booting into an unintended or non-existent kernel, rendering the system unusable. Improper setting of the default kernel is akin to setting the system to fail.
-
Verifying the Updated Configuration
Before rebooting, verifying the updated bootloader configuration is critical. The configuration file can be inspected to ensure that XanMod is no longer listed as a boot option and that the default kernel is correctly specified. This verification step helps prevent boot failures and ensures a smooth transition to the default kernel. This step helps avoid issues during reboot process.
Updating the bootloader configuration is an integral part of purging XanMod. Ensuring the correct kernel is selected at boot time, prevents system instability and provides a reliable, functional system. This step avoids errors and issues that might affect the whole system.
4. Reboot into default kernel
Rebooting into the default kernel is the culmination of removing a custom kernel like XanMod. It verifies that the system will boot correctly with the intended kernel, confirming the success of the removal process. A successful reboot is essential to ensure system stability and prevent boot failures.
-
Verifying Bootloader Changes
Prior to rebooting, it is crucial to verify that the bootloader configuration has been correctly updated.

A failure to accurately configure the bootloader will likely result in the system attempting to boot into the removed kernel, leading to a boot failure or other system errors. Proper verification is akin to a final systems check before initiating a critical procedure.
-
Initiating the Reboot Process
The reboot process should be initiated through the system’s standard reboot command (e.g., `sudo reboot`). This command gracefully shuts down the system and then restarts it, allowing the bootloader to load the configured kernel. Forcing a hard shutdown or using alternative methods may bypass the bootloader and lead to unpredictable results. Proper initiation of reboot is an essential step.
-
Monitoring the Boot Process
During the reboot, the boot process should be monitored for any errors or unusual behavior. If the system fails to boot or encounters errors, it may indicate a problem with the bootloader configuration or incomplete removal of the XanMod kernel. Early detection of these issues allows for timely intervention and troubleshooting. Failure to do so, system will fail.
-
Confirming Kernel Version
After a successful reboot, the kernel version should be verified to confirm that the system is running the intended default kernel. This can be done using the command `uname -r`, which displays the currently running kernel version. If the displayed version corresponds to the default kernel, it confirms that the removal process was successful and the system is functioning as expected. In order to maintain a system, the Kernel versions should match up.
Rebooting into the default kernel is not merely a restart; it is a validation of all preceding steps taken to remove XanMod. By confirming successful boot, ensuring stability, and verifying correct kernel selection, administrators can guarantee system functionality following custom kernel removal.
5. Verify removal completion
Verification of complete removal is the final, critical step in the process of purging XanMod. The procedure detailed in “how to purge xanmod” requires this verification to confirm the successful reversal of the installation. Failure to confirm removal can lead to latent system instability, conflicts with future updates, or continued reliance on potentially problematic kernel configurations.
