[Bug 1758924] Re: 'ssh-add -l' doesn't like the key email/comment (unlike gnome-keyring's agent used to)

[Christian Ehrhardt ]

Thanks Sebastien for re-assigning.

And thank you Nathan, for taking the time to report this bug and helping
to make Ubuntu better. I appreciate the quality of this bug report and
I'm sure it'll be helpful to others experiencing the same issue.

I agree to the triage made so far, but in that case that is not more or less than an openssh upstream feature request.
You should check if that was not resolved in the meantime. Bionic is on 1:7.6p1-4ubuntu0.3 while Current Disco Development release 19.04 is already on upstreams latest 1:7.9p1-9.

Once confirmed to be upstream bug (by checking it exists in the latest
version), the best route to getting it fixed in Ubuntu in this case
would be to file an upstream bug if you're able to do that. Otherwise,
I'm not sure what we can do directly in Ubuntu to fix the problem.

OTOH it might also be worth to check if there is some key attribute that makes it work again.
Here my current list:
$ ssh-add -l
4096 SHA256:... /home/paelzer/.ssh/id_rsa (RSA)
2048 SHA256:... ubuntu at cpaelzer-bastion (RSA)
4096 SHA256:... paelzer at lap (RSA)
4096 SHA256:... paelzer at swarm.naarz... (RSA)
You see all but the first one have the comment listed - yet I fail to see the difference as they keys look the same and id_rsa{.pub} has the same style of mentioning an id like the others that work. Never the less maybe a path for you to evaluate (or clarify with upstream).

If you do end up filing an upstream bug, please link to it from (or at
least mention it) here. Thanks!

Title:
  'ssh-add -l' doesn't like the key email/comment (unlike gnome-
  keyring's agent used to)

Status in openssh package in Ubuntu:
  Incomplete

Bug description:
  Updated today, it moved from

  2018-03-26 08:11:25 upgrade gnome-keyring:amd64 3.27.4-2ubuntu1
  3.28.0.1-1ubuntu1

  to

  2018-03-26 08:14:34 status installed gnome-keyring:amd64
  3.28.0.1-1ubuntu1


  After this, noticed that some local code that uses ssh key comments
  (from 'ssh-add -l' output) for automatic annotations is no longer
  working right.

  Previously (example from 16.04):

  nneul at skyhawk:~ $ ssh-add -l
  2048 SHA256:...... nneul at neulinger.org (RSA)

  Now (from current 18):

  nneul at infinity:~ $ ssh-add -l
  2048 SHA256:...... /users/nneul/.ssh/id_rsa (RSA)

  
  This is a negative change from my perspective as we are making use of that comment for automatic annotations (not security sensitive) and things like automatically populating git identity when managing a shared application development/server accounts.
