# Whonix support The qubes-fwupd uses the sys-whonix VM as the update VM to handle downloading updates and metadata via Tor. The tests detect if sys-whonix is running, but do not check if you are connected with Tor. So before running the test make sure that sys-whonix has access to the network. ## Refresh ```shell sudo qubes-fwupdmgr refresh --whonix ``` ## Update ```shell sudo qubes-fwupdmgr update --whonix ``` ## Downgrade ```shell sudo qubes-fwupdmgr downgrade --whonix
