    Can't create virtual monitoring interface


    I have installed Ubuntu 16.04 TLS in my Oracle virtual box.

    Now I am trying to put my USB WLAN adapter into monitoring mode which however does not work:
    sudo iwconfig wlx24050fac7ffe mode monitor 
    Error for wireless request "Set Mode" (8B06) :
        SET failed on device wlx24050fac7ffe ; Invalid argument.
    Also with airmon-ng it does not work:
    sudo airmon-ng start wlx24050fac7ffe
    Interface    Chipset        Driver
    I don't know why this is not working. The WNIC seems to be installed propoerly:
    sudo iwconfig
    lo        no wireless extensions.
    enp0s3    no wireless extensions.

    It is also recognized by the system:

    Also it is recognized when the WLAN adapter is plugged in:

    [10769.256838] r8712u 1-1:1.0 wlx24050fac7ffe: renamed from wlan0
    Do you have any ideas why I can't put the adapter with airmon-ng in virtual monitoring mode?

    Thank you.
