Hi @Monica2511 I got a similar error for ubuntu 16.04 as a solution when I researched; As seen in the commands below, the problem was solved by first updating the 3.1.29 version and then to the 4.2.0 version.

./rsid-fw-update --file F450_3.1.0.29_SKU1_SIGNED.bin --port /dev/ttyACM0 --force-version ./rsid-fw-update --file F450_4.2.0.8200_SKU1_SIGNED.bin --port /dev/ttyACM0
