I did. But when I open the module, it says the agent isn’t installed. When I click to Install, it hangs on Downloading. There’s a button for Process manual installation Synology Active Backup for Business Agent Installation Guide
Introduction
The installation file contains Linux snapshot driver and the Linux backup service.

F.A.Q.
Problem:
In the installation process the compilation of the kernel module fails, the following error is seen: In kernel headers for this kernel does not seem to be installed.
Solution:
This error has been presented to me in a FreePBX distribution (Sangoma Linux release 7.8.2003 (Core)) and this is the solution that I have found.
Step 1
The first thing is to check that we have kernel-devel installed with:
# yum install kernel-devel
Another way to check if it is installed is to look at the directory where the kernels are installed, it should look something like this:
# ls -la /usr/src/kernels/
total 4
drwxrwxrwx. 3 root root 41 Aug 19 2021 .
drwxrwxrwx. 8 root root 157 Jul 22 17:35 …
drwxr-xr-x 22 root root 4096 Jul 22 17:37 3.10.0-1127.19.1.el7.x86_64
Step 2
If all this is correct we will check if the symbolic link of “/lib/modules/{version}/build” exists.
On my system that file did not exist and because of this the kernel module that has to be compiled during the installation process shows the error message.
We create the symbolic link:
# cd /lib/modules/$(uname -r)/
# ln -s /usr/src/kernels/$(uname -r)/ build
Step 3
Since the module build process failed, trying to reinstall the update will still cause build issues.
To solve this, before starting the update process we must delete “/usr/src/synosnap-{version}/”, or do a “make clean” inside the directory “/usr/src/synosnap-{version}/”.
Opcion 1:
# rm -fr /usr/src/synosnap-*
Opcion 2:
# cd /usr/src/synosnap-{version}/
# make clean
Step 4
Once we have created this, we start the installation/update process again.
I followed the steps under FAQ. But I think the problem is the agent isn’t installed, so I’m trying to do that, I got it downloaded but need to figure out how to unzip and install it. I got the rpm file which I believe is correct for freepbx?
