This has been fixed in upstream openssh, and will be part of like 7.3 release or some such. When that gets released, makes it to debian and makes it to ubuntu, this bug will be resolved. This is a minor issue and not worth cherrypicking for. I'll just mark ubuntu task as fix released, cause we will forget to do so with 7.3 upload.

The alleged problem is the reference to /etc/ssh/primes instead of /etc/ssh/moduli. It would appear that the file /etc/ssh/primes is neither used by ssh server, nor documented. I note that this error appears to have been reported in several places on the web in the past years, but to no avail (e.g. http://misc.openbsd.narkive.com/tZPNEoZk/no-suitable-primes) Release: Ubuntu 14.04.3 LTS Package: openssh-server, Version: 1:6.6p1-2ubuntu2.3 To manage notifications about this bug go to: https://bugs.launchpad.net/openssh/+bug/1528251/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
