There are many questions around regarding ssh-agent, but none of the situations described seems to correspond to my problem.
First, I am using Lubuntu 14.04.4.
I have followed the instructions (found in arch wiki):
$ ssh-agent
$ eval $(ssh-agent)
$ ssh-add ~/.ssh/id_dsa
But when I do:
$ ssh -p 22 [email protected]
it asks for the password.
(There is an actual ip address, I just do not feel like sharing it ;-) )
I found somewhere to verify the following:
$ echo $SSH_AUTH_SOCK
/tmp/ssh-tw1EdcXYFnDd/agent.6550
which I understand as a valid output.
So what am I missing?
I also tried using ssh-pass but nothing happens.
Otherwise, I have no problem login in manually, it is just a pain in the ass to type constantly the password...
Thanks in advance.

I have replaced what I considered sensitive information by xxxxxxx or cccccccc.
Anyway thanks for asking for more info.
Update 27/05/2016: Following the observation of Waltinator that I was getting a message regarding the format of the file, I checked it, and not found any obvious mistaken. Normal, as that file has never edited by hand.
I simply give up, and generate a new password-less key and use ssh-copy-id as suggested by Julen. It works. I have marked the title as solved.
ssh -vv -p 22 [email protected]
ssh-copy-id [email protected]
