Updated to HassOS 1.7
Is it support Bluetooth LE Tracker from box? Or only Bluetooth Tracker? No information about new HassOS at https://www.home-assistant.io/components/device_tracker.bluetooth_le_tracker/ 
I havnt got it to work on Hassio / HassOS
mine works fine, it is used as a sensor. Works pretty good.
LE version?
I’m using HassOs on a raspberry pi3
I’m running Hassio 0.75.2 on HassOS 1.9.
Here’s what happens when I try to use the BLE Tracker component:
2018-08-08 17:24:43 ERROR (SyncWorker_0) [homeassistant.util.package] Unable to install package gattlib==0.20150805: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-rqqaynq_/gattlib/
You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Help, anyone? Thanks!!
You need to have ssh access and type following to fix the error message partially:
pip3 install --upgrade pip
pip3.6 install --upgrade pip
Both of them just in case, no idea which version is used so it is better to upgrade both.
But I just tested it and no luck with that. Just switched from propietary bt sensor beacon format to eddystone and having major difficulties with eddystone beacons. So figured out if I get this le tracker working, it is easier to troubleshoot further. And hitting a dead end here too.
This is what I tried:
pip install gattlib
fail, "No such file or directory: ‘pkg-config’
pip install pkg-config
pip install gattlib
And no luck, gcc is missing and installation falis. And did not find any way to install gcc so I’ll give up for now.
edit: Opened a bug before finally quitting:
