I have a problem uploading sketches to the Blinks Interface
The copied error message is:

An error occurred while uploading the sketch

avrdude done. Thank you.
Linux Mint 20 Cinnamon 4.6.7 5.4.0-73-generic
The user is already in the group “dialout”
I have 3 serial Ports
ttyACM0 ttyACM1 ttyACM2
it works with none of those
The same Blink Hardware works on an other WIN10 PC without problems.
What can I do?
