What is happening?

covalent/covalent/_file_transfer/strategies/rsync_strategy.py

Line 45 in e45bd30

if self.private_key_path and not os.path.exists(self.private_key_path):

at present it is checked for the key file in present system. However for a centrally managed dispatcher server, which runs and syncs the files in that central server, user need to provide key file path in the remote server to make it work. At present this checks raise an error, commenting out this check make it work perfectly.

How can we reproduce the issue?

self explanatory

What should happen?

should work if the logic is fixed.

Any suggestions?

Disable this check or provide an option to override. We might just want to provide an warning rather than error in this case. ALternate proposal could be to make a remote_sync class which behaves like the logic executors use.
