Legacy algorithm support

[abdelhamid-attaby]

I got the following message when trying to ssh a BlueHost server:

2020/05/23 13:43:07 ssh: handshake failed: ssh: no common algorithm for key exchange; client offered: [curve25519-sha256@libssh.org ecdh-sha2-nistp256 ecdh-sha2-nistp384 ecdh-sha2-nistp521 diffie-hellman-group14-sha1], server offered: [diffie-hellman-group-exchange-sha256]

Even when I try ssh-action@v0.0.9.

@abdelhamid-attaby Can you provide detailed steps about how to generate the ssh key?

[appleboy]

Add the algorithm to your client config:

1. open /etc/ssh/ssh_config
2. update KexAlgorithms setting and add diffie-hellman-group-exchange-sha256

[abdelhamid-attaby]

@appleboy I generated the key using the Manage SSH Keys in cPanel.

[abdelhamid-attaby]

Add the algorithm to your client config:

1. open /etc/ssh/ssh_config
2. update KexAlgorithms setting and add diffie-hellman-group-exchange-sha256

Which client config, I am using Github Actions.

@abdelhamid-attaby Can you login to your server via ssh?

[abdelhamid-attaby]

@appleboy Yes I can using a downloaded private key.

[abdelhamid-attaby]

@appleboy any idea? The KexAlgorithm should be added to the compiled ubuntu image of the ssh-action.

[appleboy]

@abdelhamid-attaby I will take it.
