to clarify: ELECTRUM_PATH should be something like this: /home/user/.New folder/whatever?
should it be in quotes?
I think first one is correct and you dont need it to be in quotes
Either option is a valid choice. But if you don't use quotes, you need to escape any space within the file path with a backslash.
"/home/user/.New folder/whatever"
#or
/home/user/.New\ folder/whatever
