Warning! GPU of your assigned virtual machine is Tesla K80.

This warning message tells you your colab machine uses Tesla K80 GPU. Google colab assign you the machine with Tesla T4, P100, or K80 randomly. remocolab show this message because K80 is oldest one and someone people want to use P100 or T4 rather than K80. If you are fine with Tesla K80, ignore this message or add parameter check_gpu_available = False to remocolab.setupVNC().

These Failed to fetch http://ppa.launchpad.net/... error messages looks like temporary server down. remocolab.setupVNC() runs system update. I think when you execute it, ubuntu package server was temporary down and you got these error. I tested remocolab.setupVNC() now and it worked without error.

Thanks for answering ! Yes, it worked later. I had problems with the ngrok not tunneling, but I changed the region and it worked just fine.

Thanks for the amazing code <3 !
