no matching key exchange method found
H!
I have a problem updating trunk having ssh with allowed DH key length 2048 and above.
Logging on: bzr launchpad-login USER
Updating trunk...
ssh_dispatch_
ConnectionReset reading response for 'BzrDir.open_2.1', retrying
ssh_dispatch_
bzr: ERROR: Connection closed: Unexpected end of message. Please check connectivity and permissions, and report a bug if problems persist.
I think it deserves special attention as ssh v.7.0 will put some limits on the key size: http://

Just got this error too. bzr worked earlier but no longer, no idea why. I'm on Windows.
| Amos Ng (amosjyng) said : | #6 |
It works again after I do
bzr config --remove launchpad_username --scope bazaar
It appears the problem only occurs when I'm logged into launchpad.

In my case - I have to be logged on as I need to submit changes to the trunk.

We know about this and are working on it; it's of special concern to me since I maintain the openssh packages as well. It's taking a little while because we need to get changes made in the Twisted project first, and then we need to organise an upgrade at our end which unfortunately brings in its own dependency chain. I've linked to the bug that tracks this.
As far as workarounds go, this comes under: http://
I've put this in my .ssh/config:
Host 91.189.95.84
No luck... This is using cygwin on Windows 10.
What is the correct workaround? It's not good that I can no longer update our branch...
| Colin Watson (cjwatson) said : | #10 |
Peter, I would expect it to have to be "Host bazaar.
After making that change, if it still doesn't work then please post the output of "ssh -vvv bazaar.
To be clear, you need:
Host bazaar.
Thanks, that helped!
| Colin Watson (cjwatson) said : | #12 |
Per my update in the linked bug, you no longer need "Host bazaar.
| Colin Watson (cjwatson) said : | #13 |
In case you haven't noticed based on updates to the linked bug: this problem is now fixed and you can simply use the default crypto settings in OpenSSH 7.1 with Launchpad servers.
Can you help with this problem?
