Non installed fleetspeak

[AWonderfulUser]

Environment

• How did you install GRR? [e.g. from release DEB, HEAD DEB, PIP package, source] Docker
• What GRR version are you running?: [e.g. 3.1.2.3] latest, 3.4.7.1
• What operating system does the GRR server run on? [e.g. Ubuntu 18.04] Debian 12
• What operating system does the affected GRR client run on, if applicable? [e.g. Windows 10] DEbian 12

Describe the issue
After downloading a grr binary on the admin dashboard, sending it to the host machine and running dpkg -i grr-client.deb, an errors pops out:

Selecting previously unselected package grr.
(Reading database ... 81183 files and directories currently installed.)
Preparing to unpack grr_3.4.7.1_amd64.deb ...
Unpacking grr (3471-1) ...
Setting up grr (3471-1) ...
Failed to get unit file state for FleetspeakService.service: No such file or directory
FleetspeakService.service is a disabled or a static unit not running, not starting it.

I think that the issue comes from the fact that no fleetspeak is installed. If I'm right, can somebody tell me if it is possible to install fleetspeak without compiling it using go?

Error logs
After a try to execute the grrd binary manually, it gives me this error

# ./grrd --config grrd.yaml

Additional context
I installed grr-server using Docker after facing a few issues while trying to install it with the deb installation, using a host MySQL server.
On the grr-server container, fleetspeak isn't running.
On the MySQL server, no modifications were made to the fleetspeak database, but everything seems to be good with the grr-server database.
After a dpkg -i on the host server, grrd files are successfully installed, but I don't see anything related to fleetspeak on my host machine.
