Hi, I am running Arduino IDE 1.8.12 under Ubuntu 16.04 Linux on a virtual machine of my Mac. Quite
often, I get errors like: Failure to open port, failure to jump start
So far, it seems that if I quite the application and restart again, the problem is solved. Anybody knows how
to fix this without having to quit and restart all the time?
Does it has to do with the modemmamager?
I tried: sudo apt-get purge modemmanager
but I got the unable to locate package modemmanager error.
