tedge connect c8y shows warnings about certificates when connect via basic auth credentials #3476
Description
Describe the bug
When connecting to Cumulocity using Basic Auth (e.g. tedge config set c8y.auth_method basic), the tedge connect c8y prints out unnecessary warnings about failing to change the ownership of the public and private certificate, which is unexpected as a device certificate is not needed when connecting via Basic Auth credentials.
Below shows the tedge connect c8y lines with the two WARN lines which should not be present when using basic auth.
root@tedge:~# tedge connect c8y

-
Configure thin-edge.io to use basic auth when connecting to Cumulocity
sudo tedge config set c8y.auth_method basic cat <<EOT > "$(tedge config get c8y.credentials_path)" [c8y] username = "t12345/device_rmi_test1001" password = "<some_password>" EOT sudo tedge config set device.id rmi_test1001
-
Connect to c8y
sudo tedge connect c8y
Expected behavior
The following log messages should not be present in the output as it is expected that the certificate files do not exist when using basic auth.
