push to GIN stops working with "Could not read from remote repository" error

[alecristia]

I've been working on a YODA analysis repo that has a nested dataset from multiple computers. All went well for a few days.

Just now, in a computer from which I successfully pushed in the past onto GIN, my request to push yielded:

(ChildProjectVenv) (base) MacBook-Air-2:tsi2017_input acristia$ datalad push --to gin

fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

What I checked:

• both the YODA repo & nested repo are accessible on GIN by me, so they exist & I have access rights
• I had successfully pushed in the past
• a search for this error in the discussions led me to how I set up an analysis repository building on a dataset (IN PROGRESS) #251 , but solutions there don't apply here

I suspect the error comes from the fact that I modified my .ssh/config file, though looking at it, I'm not sure why my changes affect this. I have a recollection that whenever you change your ssh config, your SSH public key changes. So I'll try updating that in GIN

[alecristia]

hmm no, when I go to GIN > Your parameters > SSH keys and try to add my ssh pub key as a new key, I get "Le contenu de la clé publique a été utilisée."

[alecristia]

oh something else that is probably not relevant:

The problem arose in a mac that I suspect has a git-annex problem that I haven't looked into. The files that have been modified by the commits are NOT annexed as far as I remember, but if you know how I could check, I could look into that

the error message strongly suggests a problem with the .ssh/config file like you pointed out.
Can you do any ssh operation on that computer (like ssh oberon) ?

And what is the content of the ocnfig file?

[alecristia]

you're on the right track! yes, my ssh is broken -- I'll DM you to see if you can see what I need to fix. Thank you!

The ssh config file had an error : using Username instead of User . replacing it resolved the issue
