=Introduction=
This procedure explains how to correctly update your server's kernel in case you have an Acronis Backup agent.

=Kernel and headers update=
To update the server kernel do the following command:

sudo apt-get install linux-image-`uname -r`

Then update the headers:

sudo apt-get install linux-headers-`uname -r`

You must then restart the server because a new kernel has been installed. 
Downloading the headers corresponding to the new kernel is necessary for the Acronis agent to compile in such a way as to be compatible with the new kernel on restart.

=Other case=
In case the server kernel has been updated and then restarted without the new headers, Acronis backups will fail with the following error:

[[File:Acronis snapapi error.png|500px]]

In this case, connect to the server and check the version of the running kernel:

uname -r

Then check the version of the headers present:

dpkg --get-selections | grep linux-headers

If the result does not show headers with the same version as the current kernel, then install the new headers like this:

sudo apt-get install linux-headers-`uname -r`

Finally, recompile the snapAPI with the new version by restarting the dkms service, and restarting the Acronis agent:

service dkms_autoinstaller restart
service acronis_mms restart

The backups should now work again without problems with snapAPI.

=Conclusion=
It is very strongly recommended when updating the kernel of your servers, to also update the corresponding headers. 
This avoids many application problems related to the change of kernel.
