With my MaixGo I get messages like these all the time. It is worse when there is a program running that produces a lot of serial output. Does the uploading succeed when you try a couple of times? Sometimes it helps to try to upload a couple of times right after a failed upload (so no waiting between tries), it appears that the MaixGo pauses a second or two after a fail, stopping the serial output and allowing a new upload to succeed.

Hi there,

Same problem and same messages here under linux ubuntu 18.04.2 lts running on vmware, arduino ide 1.8.9 and maixduino 0.3.10.
The program (original arduino blink led) is not running.

Same versions of arduino and maixduino on windows 10 works.
Bye.
