Getting 'repository not found' when using multiple ssh keys / github accounts

Question

I've been using the following setup for a while to switch between multiple ssh keys and github accounts.

Firstly I have two keys in .ssh/

id_rsa_work
id_rsa_work.pub
id_rsa_personal
id_rsa_personal.pub

And a config for those keys

Host personal
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_rsa_personal

Host work
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_rsa_work

And then I'm able to switch between accounts by doing

ssh -T work or ssh -T personal

and then I use two gitconfig files to auto pickup the git config.

~/.gitconfig

[user]
    name = hex6b
    email = [email protected]

[includeIf "gitdir:~/work/"]
    path = ~/work/.gitconfig

~/work/.gitconfig

[user]
        name = My work name
        email = [email protected]

The work setup seems to work fine, however the personal one will not allow me to clone new repos or push/pull existing repos.

ERROR: Repository not found. fatal: Could not read from remote repository.

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

Not sure why it's suddenly not working, maybe since github introduced personal access tokens.

I can also see both keys when I do a ssh-add -l so I don't need to add them to the ssh agent.

Do I need to do anything special with the urls from github? Usually I just copy them from the code dialog.

Yes, you do need to change the URLs. The Git FAQ explains how to do this by changing the URL in each case.

The example configuration they give looks like this:

# This is the account for author on git.example.org.
Host example_author
    HostName git.example.org
    User git
    # This is the key pair registered for author with git.example.org.
    IdentityFile ~/.ssh/id_author
    IdentitiesOnly yes
# This is the account for committer on git.example.org.
Host example_committer
    HostName git.example.org
    User git
    # This is the key pair registered for committer with git.example.org.
    IdentityFile ~/.ssh/id_committer
    IdentitiesOnly yes

In this case, the hostname would be example_author or example_committer instead of git.example.org.
