internal inconsistency

[wmtdpl]

Download file from sftp 1.10.1, appear this：
ssh: handshake failed: ssh: no common algorithm for key exchange; client offered: [[email protected] ecdh-sha2-nistp256 ecdh-sha2-nistp384 ecdh-sha2-nistp521 diffie-hellman-group14-sha1], server offered: [diffie-hellman-group-exchange-sha256]

I add the KeyExchange to ClientConfig
sshconfig := ssh.Config{}
sshconfig.SetDefaults()
sshconfig.KeyExchanges = append(
sshconfig.KeyExchanges,
"diffie-hellman-group-exchange-sha256",
"diffie-hellman-group-exchange-sha1",
)

	configTmp := &ssh.ClientConfig{
		Config: sshconfig,
		User: client.User,
		Auth: []ssh.AuthMethod{
			ssh.Password(client.Password),
		},
		HostKeyCallback: ssh.InsecureIgnoreHostKey(),
	}

Then an error message appears：internal inconsistency
I found that the size of maxpacket is 1 << 15（322768）, but the downloaded file size is 32769， In fact, the file size is greater than 32769. It seems that only one package has been downloaded.
Is there a way to solve this problem?
thanks

This problem is due to an upstream bug in the x/crypto/ssh library for which I've already filed a bug golang/go#32075. I'm closing this as a duplicate of the issue that had me file the upstream issue, #287.
