Have you pushed down the "boot"-Button while programming?

it looks like this:

in don's picture, there is "Could not open port {}"
message and this is
- the port is not available
-- cause the guest system used it in other application
-- cause, the host system blocks
-- cause, the host system used it itself
-- cause the host system has no port of this

Don
if you use a vm
be sure your host system ( ubuntu ) has privileg open and allowed
to use your hardware in the "guest" system ( ubuntu in vm )
example here a vm on windows ( host ) and using a ubuntu (guest)
and there is no privileg open and allowed hw peripheral

right click in the vm on the usb sysmbol right buttom corner
you see example this, that there is no given hw to the guest system
after select a hw and privileg to open and allowed

you see the hw in the guest system and you can use it.
from now, the host system has no privileg to use it
if you want use it again, you must deactivate in the VM system again.
if you have forget to close your hw serial in the HOST system
you can not use it in the GUEST system
your picture looks like
you have no serial adapter in the "GUEST" system
if you want install HW in the GUEST system
then you have to allow it in the HOST system first to install it in the GUEST system
for the serial drivers there are advanced packs from Oracle available
you must install usb pack for the "VM"
thats the sence of a VM sytsem
best wishes

btw:
i use here in this example DevKitC V2
you see no Silicon Labs CP 21xx or orther things in the Guest system
you see it in the HOST system, that "forward" the HW to the guest system
in my example with Windows as Hostsystem and Ubuntu as Guest System as "Sierra Wireless mini card"
like Angus say
in your example you use ubuntu as Host system
there is usually support for the Silicon Labs CP from kernel
if you want us it, you do not need ( you can not ) install an "extra driver" in the Guest system.
you allways do things over the HOST sytem first, for this, Oracle have advanced packs for USB2, USB3 and so on.
in my example ( Windows as Host system )
i must use the "windows name for com serials"
i can not use /dev/ttyUSB0
i must use COMx
right, also in the Guest system, i must use COMx not /dev/ttyUSB0
