[Bioc-devel] troubles with fetching Bioconductor github

[Piotr]

Dear All,

I try to follow instruction here:
https://bioconductor.org/developers/how-to/git/sync-existing-repositories/

however, I find the following
git fetch --all
Fetching origin
Fetching upstream
sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
error: Could not fetch upstream

I have correct ssh keys and I am almost sure about 1 hr ago it worked.
What might have happened?

I created new ssh key but it is still not working

Kind regards,
Piotr
