Inconsistent Debian kernel versions. Please try installing kernel header files manually.

When installing Fort Tower Enterprise Tamper-Proof, it was prompted that the current kernel version was inconsistent. Please try to update the system. I believe many friends have encountered such a situation. The following are the steps to fix and solve this problem:

Warm reminder: It is recommended to back up the server system before operating to avoid irreversible situations.

To manually install a specific version of the kernel header file, take version 6.1.0-31-amd64 as an example, please follow the following steps:

1. Confirm package availability

apt list -a linux-headers-6.1.0-31-amd64

Check if the version is available in the warehouse

If it is not listed, you need to add the security update source first or download it manually

2. Install the specified version of the kernel header file

#Install Command

sudo apt install linux-headers-6.1.0-31-amd64 -y

#If you cannot find the package, update the source first

sudo apt update

sudo apt install -t bookworm-security linux-headers-6.1.0-31-amd64 -y

3. verify the installation

#Check installed header files

dpkg -l | grep 'linux-headers-6.1.0-31-amd64'

#View file location

ls /usr/src/linux-headers-6.1.0-31-amd64

4. Associate the kernel image (if not already installed)

#Install the matching kernel image

sudo apt install linux-image-6.1.0-31-amd64 -y

#Rebuild kernel module dependencies

sudo depmod -a

5. Update boot configuration

#Update initramfs

sudo update-initramfs -u -k 6.1.0-31-amd64

#Update GRUB

sudo update-grub

6. restart the system

sudo reboot

After the above operations, after reinstallingFort Tower enterprise-level tamper-proof is enough.
