In the Linux version of Electrum 3.3.7 and 3.3.8, when I type ./run_electrum in Linux Mint 17, I get this error message:
File "./run_electrum", line 67
sys.exit(f"Error: {str(e)}. Try 'sudo python3 -m pip install '")
^
SyntaxError: invalid syntax
Once in a while you should try running your own code! And while you're at it, why don't you fix the problem in electrum version 3.2.3 that causes it to say "synchronizing..." regardless of what server it's connect to. AND POST AN EMAIL ADDRESS ON ELECTRUM.ORG SO YOU CAN BE CONTACTED!!!!
