Hello,

i just tried to install the falcon sensor on my pve 9 host.
It fails with some dependency errors:


Code: 
Unpacking falcon-sensor (7.38.0-19102) ...
dpkg: dependency problems prevent configuration of falcon-sensor:
 falcon-sensor depends on libnl1 | libnl-genl-3-200; however:
  Package libnl1 is not installed.
  Package libnl-genl-3-200 is not installed.

dpkg: error processing package falcon-sensor (--install):
 dependency problems - leaving unconfigured
Processing triggers for libc-bin (2.41-12+deb13u3) ...
Errors were encountered while processing:
 falcon-sensor

Is there a safe way to install the falcon sensor on a PVE 9.2.3+ Host?
Or should i do not do this because there a known issues installing falcon sensor on my hypervisor?

Best regards,
holger

How did you try to install it? At least libnl-genl-3-200 exists in debian Trixie.
 
PVE UI -> Console -> dpkg -i falcon-sensor_7.38.0-19102_amd64.deb

root@*******:/opt# cat /etc/os-release

You will need to follow up that dpkg command with an `apt-get --fix-broken install` for apt to pick up missing dependencies.

Are you following some kind of manual during that installation? I would expect that manual to cover that aspect.

I have no clue what that piece of software is going to do to your PVE cluster, but with the most prominent CrowdStrike-related news headlines in mind I'd be surprised if it was any good.

Think of PVE as an appliance, especially if you have not installed it on a vanilla Debian base.

Can you install almost anything on Linux - yes. Have we seen Crowdstrike bring down quarter of the world IT - yes. Have they fixed _known_ bugs - yes.

As for installation errors, it would be better if you provided the entire output, including the command you run to initiate the installation and any preceding commands specified by the vendor.

Hey guys. thank you for your reply.
I hab a typo with installing libnl-genl-3-200 ... My fault...

thank you
 
Install deb via apt and take care of the dependencies with (path can also be relative)

Code: 
apt install /path/to/deb/file/install.deb

I don't know since when this works, but it does.
