Add an ssh key should allow adding a key without comments

[Maftoul Samuel]

In id_[r,d]dsa.pub the last part of the key line is a comment.
Launchpad should allow adding a key without a comment.
The comment is generally the username@hostname used when the key was created, this doesn't add any usefull information to launchpad

Just had another user on #launchpad affected by this.

[Magnus Hedemark (viridari)]

I was banging my head against the wall with the same problem. Was trying to add a known good public key, one which does not include a comment field (valid per OpenSSH specifications and common in the real world) and Launchpad refused to accept it as a valid key. I added a bogus comment to the end of it per the suggestion of "spiv" (Andrew Bennetts) in #launchpad and it worked.

This bug is getting pretty long in tooth. Could someone please have a look at it?

[Peter Antoniac (pan1nx)]

Agreed. This is still a bug and if it cannot be fixed, it could be fairly easy to add some comments/info to help the user add the key with a comment.

[Vagrant Cascadian (vagrantc)]

this was a bit frustrating for me too... if it is for some reason unfixable, at least improve the error message and/or documentation on adding keys to mention this bug.

[Renne (renne)]

It was quite frustrating for me, too. I had to find the reason by googling after a successless series of try-and-errors.

It's quite embarrasing for Canoncial to habe this BUG still open after SEVEN years.

At least, add a hint in the error message!

Note that i even wrote a verification routine in the trail of https://bugs.launchpad.net/launchpad/+bug/540195 that would handle this fine: https://bugs.launchpad.net/launchpad/+bug/540195/comments/6
