Package: openssh-client Version: 1:7.6p1-2 Severity: important File: openssh
This is not the machine which shows this error; I was unable to install reportbug there due to: reportbug : Depends: python3-reportbug (= 7.1.7+deb9u2) but it is not going to be installed On that other machine, any mention of chacha20-poly1...@openssh.com in the Ciphers list before an alg which both sides support prevents cipher negotiation. Other stretch machines work fine (including this one, which already had reportbug installed). The other machine is also on 1:7.6p1-2, and is configured very similarly. One interesting thing from -vv output, is that it ends with: Unable to negotiate with IP.ADD.RE.SS port NUM: no matching cipher found. Their offer: aes128-ctr,aes192-ctr,aes256-ctr,aes128-...@openssh.com,aes256-...@openssh.comssh.com,aes256-...@openssh.com Note the aes256-...@openssh.comssh.com in there. -- System Information: Debian Release: stretch APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-042stab127.2 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages openssh-client depends on: ii adduser 3.116 ii dpkg 1.19.0.5 ii libc6 2.25-6 ii libedit2 3.1-20170329-1 ii libgssapi-krb5-2 1.15.2-2 ii libselinux1 2.7-2 ii libssl1.0.2 1.0.2n-1 ii passwd 1:4.5-1 ii zlib1g 1:1.2.8.dfsg-5 Versions of packages openssh-client recommends: pn xauth <none> Versions of packages openssh-client suggests: pn keychain <none> pn libpam-ssh <none> pn monkeysphere <none> pn ssh-askpass <none> -- no debconf information
