Centos electrum public-key import

I have several bitcoin addresses (together with corresponding public keys) from Electrum wallet I’ve used previously. I moved to another CentOS server and now I need to import this addresses back.
But when I do:

electrum sweep [public key] [btc address] -w [path to wallet]

I get:

Traceback (most recent call last):
File "/usr/local/bin/electrum", line 384, in <module>
result = server.run_cmdline(config_options)
File "/usr/local/lib/python3.7/site-packages/jsonrpclib/jsonrpc.py", line 748, in __call__
return self.__send(self.__name, args)

What am I doing wrong?
