Programming mote using TinyOS getting error (Ubuntu 18.04)

I'm programming the MSP-430 mote using the command telosb. I'm stumbled in the error showed below:

root@andrea-VirtualBox:/etc/apt/sources.list.d/tinyos-main/apps/Blink# make telosb reinstall bsl,/dev/ttyUSB0
cp build/telosb/main.ihex build/telosb/main.ihex.out
    installing telosb binary using bsl
tos-bsl --telosb -c /dev/ttyUSB0 -r -e -I -p
build/telosb/main.ihex.out

/etc/apt/sources.list.d/tinyos-main/support/make/msp /bsl.extra:45: recipe for target 'program' failed

How can I solve this?
I'm spending days on that :(
