When do you need this to be done by? (YYYY/MM/DD) I'm not in a rush

my fork is
ssh://git@pagure.io/forks/rlengland/fedoramagazine-images.git

That should be 'fork' there not 'forks' right?
ie, it's:
https://pagure.io/fork/rlengland/fedoramagazine-images

I can successfully clone the repo and check out. But when I make my addition, add it, and commit it and then try to do my "push" I get the following ('tbird-filters' is my branch name):

$ git push origin tbird-filters
sign_and_send_pubkey: signing failed for RSA "/home/rengland/.ssh/id_rsa" from agent: agent refused operation
git@pagure.io: Permission denied (publickey).
fatal: Could not read from remote repository.

This is usually caused by your local ssh-agent being broken/dead/not having your keys loaded into it.

If you logout and back on does it start working?

Does 'ssh-add -L' show your ssh public key?

Have you changed your ssh key recently? If so, have you updated it in your prefs on pagure.io?

Sorry for the length of this addition but I want to give you as much info as I can

=============Logged out and back in but I get the same results.
$ ssh-add -L
ssh-rsa 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 rengland@morse

==============This is the key I entered in my account at
https://pagure.io/settings#nav-ssh-tab

I did this as a cut and paste and I noted that the embedded '/'
characters seemed to cause line breaks in the text entry box when I
added it, as it did in the text above. I don't know if that is a problem but I don't see a way
around it unless I need to escape them in some manner.

=============prefs on pagure.i

=============I use this to create my local repo
$ git clone https://pagure.io/fedoramagazine-images -o upstream
=============and the repo is created

=============The fork I am working from is shown on the web page as
https://pagure.io/fork/rlengland/fedoramagazine-images

=============on that page the Clone drop down shows
ssh://git@pagure.io/forks/rlengland/fedoramagazine-images.git

=============I use that address here
$ cd fedoramagazine-images
$ git remote add orign ssh://git@pagure.io/forks/rlengland/fedoramagazine-images.git

=============Then
$ git checkout master
Already on 'master'
Your branch is up to date with 'upstream/master'.

$ git checkout -b Tbird-filters
Switched to a new branch 'Tbird-filters'

=============Did some work and added a file ....

$ git add images/Tbird_mail_filters.svg

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

Would you by any chance the possibility to drop by #fedora-admin on freenode and ping me? I think it would help if we can debug this "live". I'll keep looking through the logs and the system in the meantime to see if I can find something

Issue resolve by correctly setting the permission on the .ssh directory and it's contents.
