Solve the following python programming problem given the following code:
@ property 
def users(self) : 
    def validate_pass_encoding(password) : 
        try : 
            password.encode ('ascii') 
except (UnicodeDecodeError, UnicodeEncodeError) : 
            raise ConanException ('Password contains invalid characters. Only ASCII encoding is supported') 
return password 
if self.env_config ['users'] : 
        pairs = self.env_config ['users'].split (',') 
        return { pair.split (':') [0] : validate_pass_encoding (pair.split (':') [1]) for pair in pairs } 
else : 
        tmp = dict (self._get_file_conf ('users')) 
        tmp = { validate_pass_encoding : validate_pass_encoding (value) for (key, value) in tmp.items () } 
        return tmp 

    
    

    Fix the buggy line: tmp = { validate_pass_encoding : validate_pass_encoding (value) for (key, value) in tmp.items () }

#Here is Python code to fix the buggy line: tmp = { validate_pass_encoding : validate_pass_encoding (value) for (key, value) in tmp.

tmp = { key : validate_pass_encoding (value) for (key, value) in tmp.items () }
