[SOLVED] Help needed to install Malwarebytes agent on proxmox 7.4-3. Kernel headers issue

[kumarullal]

I did apt-get upgrade
and apt-get dist-upgrade
Since I did apt-get dist-upgrade today, I must have installed the latest kernel as of today. Insted, this is what I am getting.
uname -r
5.15.30-2-pve
Installed kernel headers by issuing command :
apt install pve-headers-5.15.30-2-pve

However, the linux agent didnt get installed.

When I did some digging, this is what I found
dpkg -l | grep 5.15.30

out put is this :

ii pve-headers-5.15.30-2-pve 5.15.30-3 amd64 The Proxmox PVE Kernel Headers
ii pve-kernel-5.15.30-2-pve 5.15.30-3 amd64 The Proxmox PVE Kernel Image

Why 5.15.30-3 ??

Also when I ran:
pveversion -v
proxmox-ve: 7.4-1 (running kernel: 5.15.30-2-pve)
pve-manager: 7.4-3 (running version: 7.4-3/9002ab8a)
pve-kernel-5.15: 7.3-3
pve-kernel-5.15.102-1-pve: 5.15.102-1
pve-kernel-5.15.85-1-pve: 5.15.85-1
pve-kernel-5.15.30-2-pve: 5.15.30-3
......

What am I doing wrong?

Thanks in advance.

If you did not install the PVE kernel headers, using apt install pve-headers will install pve-headers-5.15 and the headers for the latest 5.15. kernel. Since you are running the oldest kernel that is installed, use apt install pve-headers-5.15.30-2-pve to install the Linux kernel headers that match that kernel version.

Hi @leesteken
Thanks for your reply. I have used

apt install pve-headers-5.15.30-2-pve

PVE headers and PVE Kernel headers both show pve-headers-5.15.30-2-pve 5.15.30-3
I have not restarted the server after dist-upgrade and installing Kernel headers. Would that make any difference?

Unless you make sure it boots the same old kernel, Proxmox will probably boot the latest kernel version you have installed. And then you'll have to install the headers for that kernel version and build the software for that kernel version and reboot again.

It is working now. I was making a mistake in installing the linux agent.
Thanks
