How correct fix this error?
Package don`t have application pgqadm.py

Answer 1

You must use the name you gave the node, not its ip.
for example if you create the node
londiste3 slave.ini create-branch slave 'SLAVE_CONN_STR' --provider = 'MASTER_CONN_STR'
you delete the node with
londiste3 slave.ini drop-node slave
