Flash erase error -71 has occured

[ziggo457]

I'm getting this error all the time with Digispark. 1 out of 10 times it works, then again not working. Always this error..

I use these instructions: https://docs.arduino.cc/software/ide-v1/tutorials/Linux

When I try $ sudo ls -l /dev/ttyACM*
It returns: ls: cannot access '/dev/ttyACM*': No such file or directory

I put user in groups 'dialout' and 'tty'.

Hi!
Today I have faced the same issue. Digispark board does not create its own serial port (unlike usual Arduino). Looks like a hardware trubles.
Which USB port are you trying to use (USB3/USB2)?
UPD: also attach you Digispark via usb an watch what is going on in "journalctl -f"
UPD #2: Finally i figured out a root cause of this issue: digispark uploader cannot work correctly with USB 3.0. I have checked out to USB 2.0 and everything became fine.
