SSH Entry with Key Not Accepting

Initial Setup:

  1. Setup ssh keys and disable passwords-based authentication via ssh (the most secure)

Instead option 3, I choose option 1.

I try to follow the given procedure as below,

configtargetssh 192.168.2.2
Generating new key pair…
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/mangoh/.ssh/id_rsa.legatoTarget.
Your public key has been saved in /home/mangoh/.ssh/id_rsa.legatoTarget.pub.
The key fingerprint is:
SHA256:xPpvnp9qkqaX0skd2ONVS/zoUUCC20gnib8kV3an8QE mangoh’s key for Legato target devices.
The key’s randomart image is:

Adding the target to the list of known hosts.

Connecting to the target… (ENTER TARGET’S ROOT PASSWORD WHENEVER PROMPTED FOR A PASSWORD)
(Just hit ENTER if your target doesn’t have a root password.)
/home/mangoh/.ssh/config line 5: Bad SSH2 cipher spec ‘aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,aes192-cbc,aes256-cbc,blowfish-cbc’.

When i am entering

ssh root@192.168.2.2

I am getting like this

/home/mangoh/.ssh/config line 5: Bad SSH2 cipher spec ‘aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,aes192-cbc,aes256-cbc,blowfish-cbc’.

Please help me to resolve the problem…
