no matching key exchange method found.

I am trying to copy my build Artifacts to my Linux Server using azure-piplines and this task:

- task: CopyFilesOverSSH@0
  inputs:
    sshEndpoint: 'pillbox'
    sourceFolder: '$(build.artifactstagingdirectory)'
    contents: 'AmiKoWindows/bin/Release/Amiko-Installer/Amiko-Installer.msi'
    targetFolder: '/home/ftp/Amiko_Desitin_Win7.msi'

The SSH Copy-Job always fails. My SSH log on the receiving end says:

Jun 12 16:02:15 [sshd] Unable to negotiate with 137.135.130.50 port 1984: no matching key exchange method found. Their offer: ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1 [preauth]

I use Ed25519 which is the most recommended public-key algorithm available today.

any thoughts on when Azure-Pipeline-Tasks may support that? The offered key exchange methods seem a bit outdated AFAICT.

Hi everyone! Current ‘ssh2’ version for CopyFilesOverSSHV0 task is 1.4.0, which should resolve this issue - please let us know if you still see it.
