Multiple ssh keys are not working

OS Description: Ubuntu 14.04.3 LTS
ssh: OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.3, OpenSSL 1.0.1f 6 Jan 2014

I am unable to use multiple ssh key for gitlab. The error I am getting is

GitLab: The project you were looking for could not be found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists. 

I am pretty much sure that I did everything right This is my config file

Host work gitlab.com
    Hostname gitlab.com
    IdentityFile ~/.ssh/ida_rsa
    User git

Host integrate gitlab.com
    Hostname gitlab.com
    IdentityFile ~/.ssh/ida_rsa_personal
    User git

The keys are added automatically in ssh-agent, but to make sure I also added the key manually

$ ssh-add -l
2048 e7:08:d6:8c:00:28:31:f9:3f:21:4a:0f:4e:1e:ee:20 id_rsa (RSA)
2048 ff:22:f6:90:2b:7c:9f:ed:45:41:df:79:06:de:fe:81 id_rsa_personal (RSA)

My ssh-agent is also running

$ ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-uTC6tA5HMt1x/agent.4899; export SSH_AUTH_SOCK;
SSH_AGENT_PID=4900; export SSH_AGENT_PID;
echo Agent pid 4900;

Permissions of ssh key

-rw-------  1 yogi yogi  1679 jun 25 15:38 id_rsa
-rw-------  1 yogi yogi  1679 ago 25 10:53 id_rsa_personal
-rw-r--r--  1 yogi yogi   404 ago 25 10:53 id_rsa_personal.pub
-rw-r--r--  1 yogi yogi   391 jun 25 15:41 id_rsa.pub

I added my ssh public key on gitlab.

Could any one please tell me what I am missing ?

Note :- I noticed that out of my two ssh keys, the ssh key which is on top( id_rsa - e7:08....) works fine.

$ ssh-add -l
**2048 e7:08:d6:8c:00:28:31:f9:3f:21:4a:0f:4e:1e:ee:20 id_rsa (RSA)**
2048 ff:22:f6:90:2b:7c:9f:ed:45:41:df:79:06:de:fe:81 id_rsa_personal (RSA)

If I add id_rsa_personal(ff:22..) after id_rsa, than id_rsa_personal starts working fine and id_rsa stops working.

$ ssh-add -l
**2048 ff:22:f6:90:2b:7c:9f:ed:45:41:df:79:06:de:fe:81 id_rsa_personal (RSA)**
2048 e7:08:d6:8c:00:28:31:f9:3f:21:4a:0f:4e:1e:ee:20 id_rsa (RSA)

I think , ssh-agent is unable to iterate through keys. It only reads first key and stops. Is this a bug in openssh ? If yes, any workaround ?

Thanks

You need to have ~/.ssh/config file

Inside file

# Default GitHub user
Host github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/personalid

# Work user account
Host bitbucket.org
    HostName bitbucket.org
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/workid

Details can be found in the link below https://confluence.atlassian.com/bitbucket/configure-multiple-ssh-identities-for-gitbash-mac-osx-linux-271943168.html

If the domain is same, use different Host

Host work.gitlab.com
    HostName gitlab.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa.work

Host home.gitlab.com
    HostName gitlab.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa.home

Clear the cache

ssh-add -D

Add all ssh keys

ssh-add ~/.ssh/id_rsa.work
ssh-add ~/.ssh/id_rsa.home

Also set your repos' url in (.git/config) accordingly as given:

url = [email protected]:xxxxxxxxxx.git
url = [email protected]:yyyyyyyyy.git 

If your ssh config file is as what I suggested.
