Solve the following python programming problem given the following code:
def get_total_capacity(self) : 
    def _get_capacity(node, zone) : 
        pod_re = re.compile ('.*pods:\\s+(?P<pods>\\d+)') 
        split = node.split () 
        if (len (split) > 0) : 
            node_name = split [0] 
            cmd = ['kubectl.sh', 'describe', 'node', node_name] 
            output_lines = subprocess.check_output (cmd).split ('
') 
            match_lines = [pod_re.search (l) for l in output_lines if pod_re.search (l)] 
            if match_lines : 
                return int (match_lines [0].group ('pods')) 
return 0 
return 0 
caps = self._nodes_command (caps) 
    return sum (caps) 

    
    

    Fix the buggy line: caps = self._nodes_command (caps)

#Here is Python program to fix the buggy line: caps = self.

caps = self._nodes_command (def _get_capacity()
