Solve the following python programming problem given the following code:
def execute(self, ns, package, _repoid = None, _installed = False) : 
    def _render_installed(package) : 
        result = 'No' 
        if ((software.get_backend (ns) == software.BACKEND_YUM) and (package.InstallDate is not None)) : 
            result = package.InstallDate.datetime.strftime ('%a %b %d/%Y  %H:%M') 
else : 
            if ((software.get_backend (ns) == software.BACKEND_PACKAGEKIT) and software.is_package_installed (package)) : 
                result = 'Yes' 
return result 
properties = ['Name', ('Arch', 'Architecture'), 'Version', 'Release', ('Summary', 'Caption'), ('Installed', _render_installed), 'Description'] 
    pkgs = [p.to_instance () for p in software.find_package (ns, pkg_spec = package, repoid = _repoid)] 
    pkgs = [p for p in pkgs if ((not _installed) or software.is_package_installed (pkgs))] 
    if (len (pkgs) < 1) : 
        raise errors.LmiFailed (('No such package "%s" found.' % package)) 
if (len (pkgs) > 1) : 
        LOG ().warn ('More than one package found for "%s" : %s', package, ', '.join ((p.ElementName for p in pkgs))) 
return (properties, pkgs [(- 1)]) 

    
    

    Fix the buggy line: pkgs = [p for p in pkgs if ((not _installed) or software.is_package_installed (pkgs))]

#Here is Python program to fix the buggy line: pkgs = [p for p in pkgs if ((not _installed) or software.

pkgs = [p for p in pkgs if ((not _installed) or software.is_package_installed (p))]
