I really appreciate you're taking some time to answer this. However, there's some confusion here: you're answering in this thread to another issue which is located in another thread (https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1522190). My configuration is not the same. could you try to reproduce the new issue with my new settings and answer in the new thread?
In the meantime, I'll post more information about sshd_config & ssh_config in the new thread. You were right: I'm not using a default configuration, but openssh should also work in other situations that the default one, right? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1497263 Title: Unable to negotiate a key exchange method Status in openssh package in Ubuntu: Incomplete Bug description: Client: Ubuntu Server 15.04 with openssh-client 6.7p1 Server: Ubuntu cloud server 15.04 with openssh-server 6.7p1 Connection trace: root@msi-ge60-ubuntu:/media/actionmystique/SAMSUNG-Ext4/KVM-Qemu/VMs# ssh -v -p 22 -i ./KVM-Ubuntu-Server-15.04-ubuntu-id_rsa ubuntu@172.16.100.245 OpenSSH_6.7p1 Ubuntu-5ubuntu1.3, OpenSSL 1.0.1f 6 Jan 2014 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 172.16.100.245 [172.16.100.245] port 22. debug1: Connection established. debug1: key_load_private_type: No such file or directory debug1: key_load_private_cert: No such file or directory debug1: key_load_private_cert: No such file or directory debug1: key_load_private_cert: No such file or directory debug1: key_load_private_cert: No such file or directory debug1: key_load_private_type: No such file or directory debug1: permanently_set_uid: 0/0 debug1: identity file ./KVM-Ubuntu-Server-15.04-ubuntu-id_rsa type 1 debug1: key_load_public: No such file or directory debug1: identity file ./KVM-Ubuntu-Server-15.04-ubuntu-id_rsa-cert type -1 debug1: identity file /root/.ssh/id_rsa type 1 debug1: key_load_public: No such file or directory debug1: identity file /root/.ssh/id_rsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.7p1 Ubuntu-5ubuntu1.3 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.7p1 Ubuntu-5ubuntu1.3 debug1: match: OpenSSH_6.7p1 Ubuntu-5ubuntu1.3 pat OpenSSH* compat 0x04000000 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-sha1 none debug1: kex: client->server aes128-ctr hmac-sha1 none Unable to negotiate a key exchange method Am I missing something?
