Updating 1.4 To Latest Version

If you use the XDP bridge, traffic will stop passing through the bridge during the update (XDP bridge is only operating while lqosd runs).

If you installed with Git

1. Change to your LibreQoS directory (e.g. cd /opt/LibreQoS)
2. Update from Git: git pull
3. Recompile: ./build-rust.sh
4. sudo rust/remove_pinned_maps.sh

Run the following commands to reload the LibreQoS services.

sudo systemctl restart lqosd
sudo systemctl restart lqos_node_manager
sudo systemctl restart lqos_scheduler

If you installed through the APT repository

All you should have to do in this case is run sudo apt update && sudo apt upgrade and LibreQoS should install the new package.
