    # Remove USB Guard From Ubuntu

    If you're a sucker like me and installed usbguard on a Ubuntu variant you may find that you will have access to none of your usb devices at all, because F you. The installer automatically sets up the daemon which has no rules so will just block all of your devices. Doing a basic `apt remove usbguard` may fail at 25%, because also F you.

    My kernel is version 4.15.0-47-generic, not sure if this stopped working at some point or what.

    ## Regain Access

    sudo echo "allow id *:*" > /etc/usbguard/rules.conf
    sudo sed -i 's/PresentDevicePolicy=apply-policy/PresentDevicePolicy=allow/' /etc/usbguard/usbguard-daemon.conf
    sudo reboot

    Reboot may hang at stopping usbguard, again, because F you. Power off or wait. You'll hopefully have access to your devices when your machine comes back up.

    ## Stop & Disable Services

    sudo systemctl stop usbguard.service
    sudo systemctl disable usbguard.service
    sudo systemctl stop usbguard-dbus.service
    sudo systemctl disable usbguard-dbus.service

    ## Uninstall and Purge

    sudo apt remove usbguard -y
    sudo apt purge usbguard -y
