Ubuntu 24.04 - Veeamsnap

[ksl28]

Hi,

I have installed the Veeam agent for Linux on 3 different freshly installed Ubuntu 24.04 servers, and they all report the same issue - Failed to load module [veeamblksnap]
I initially did this from a VBR server that manages a computer / protection group, and thought that was the issue.
So i removed it again, and then installed it manually - but saw that it also reports an issue.

Hello Kristian,

Are you running those machine with SecureBoot enabled?

[ksl28]

Hi Rovshan,

Yes according to mokutil --sb-state​, then SecureBoot is enabled.
Is that the issue?

[rovshan.pashayev]

You need to install certificate and enroll MOK, so module can be loaded.

See the the following topic, where I posted several instructions: veeam-agents-for-linux-mac-aix-solaris- ... 90746.html

Also see the User Guide: https://helpcenter.veeam.com/docs/agent ... _boot.html

Let me know the results.

[ksl28]

Hi Rovshan,

I have tried your guide, but i am never asked to set the MOK password.
So far i have done this:

Code: Select all

wget https://repository.veeam.com/.private/deb/veeamsnap/veeamsnap_6.2.0.101_all.deb

Downloaded the veeam repo, and ran this - dpkg -i ./veeam-release* && apt-get update

Veeam cant be installed because veeamsnap is not available

Hello Kristian,

Veeamsnap module is supported up to Linux kernel 5.18
The Blksnap module is supported for Linux kernels starting from 5.10

See also offline installation guide: https://helpcenter.veeam.com/docs/agent ... ver=60#deb

[ksl28]

I have executed this:

Code: Select all

apt-get remove veeam veeam-libs veeamsnap

wget https://repository.veeam.com/backup/linux/agent/dpkg/debian/public/pool/veeam/b/blksnap-dkms/blksnap_6.2.0.101_all.deb
wget https://repository.veeam.com/backup/linux/agent/dpkg/debian/public/pool/veeam/v/veeam-libs/veeam-libs_6.2.0.101_amd64.deb
wget https://repository.veeam.com/backup/linux/agent/dpkg/debian/public/pool/veeam/v/veeam/veeam_6.2.0.101_amd64.deb

apt-get install ./blksnap_6.2.0.101_all.deb
apt-get install ./veeam-libs_6.2.0.101_amd64.deb
apt-get install ./veeam_6.2.0.101_amd64.deb

I installed blksnap instead of veeamsnap, since thats what mentioned in the guide - https://helpcenter.veeam.com/docs/agent ... ver=60#deb

Little did it help - the backup still fails when triggered from a 12.2 VBR server - Failed to load module [veeamblksnap].

[rovshan.pashayev]

Did you follow instruction after installations? https://helpcenter.veeam.com/docs/agent ... nel-module

[ksl28]

I am unsure what the instructions are exactly - but i rebooted the VM, and entered the encryption password (the VM was installed with an encryption password for booting).
But there were no MOK enrollment or similar, like in the screenshots.

Any suggestions?

[rovshan.pashayev]

Hi,

During blksnap installation you should get following step, where you input password, which you would use for enrolment during reboot:



After that installing veeam-libs & veeam packages, module will load as expected:



As troubleshoot, after reboot try to load module manually:

Code: Select all

# modprobe veeamblksnap

[ksl28]

Thanks for the support, but it still doesnt work.

If i understand it correctly, then during this step, i should get a pop-up?

[rovshan.pashayev]

Hello,

Yes during blksnap package installation, you should get pop up message with password input step:

Code: Select all

apt-get install ./blksnap_6.2.0.101_all.deb

Try following:

1. Remove all packages
2. Install blksnap_6.2.0.101_all.deb
3. If you still do not get that pop up message, check following files if exist:

Code: Select all

ls -l /var/lib/shim-signed/mok/
total 8
-rw-r--r-- 1 root root  927 Sep 21 10:22 MOK.der
-rw------- 1 root root 1704 Sep 21 10:22 MOK.priv

4. If so, run following command, which will ask password prompt:

Code: Select all

mokutil --import /var/lib/shim-signed/mok/MOK.der

5. Reboot the machine and catch MOK enrollment (blue) screen
6. Enroll with password which you input in the step 4
7. After reboot install veeam-libs & veeams packages
8. Test simple backup job

Let me know the result.

[ksl28]

Awesome - this command did the trick!

Code: Select all

mokutil --import /var/lib/shim-signed/mok/MOK.der

I have tested this across all 3 servers now, and it worked flawlessly on all of them.

Could this be a bug ?

[rovshan.pashayev]

Hello,

Happy to hear that all worked for you.
This is not a bug, and User Guide has this information already: https://helpcenter.veeam.com/docs/agent ... nel-module

[Ubuntu 22.04 and later] After you install the Veeam kernel module, the key is generated and imported into your system automatically. By default, the key is stored in the /var/lib/shim-signed/mok directory.
