Cannot push to different owner repository

[eyesofjeremy]

I maintain a couple bitbucket repositories, and I had to adjust my access credentials after the March 1 2022 switch. It seemed to work ... okay.

But since then I picked up a project I was working on in 2020, with a repository that a different owner ("OtherUser") maintains. I have not been able to push my changes into that repository.

Thus far, I have undertaken the following steps:

• added my own app password
• tried supplying the app password when pushing from Sourcetree (note, this seemed unlikely, as the message at that point was looking for the password for the OtherUser)
• had the other owner remove my access and then grant it again
• received admin credentials to the other repository
• added my own SSH key to my account
• cleared the user.password in my local Git settings
• confirmed I can push to other repositories after accessing Bitbucket via SSH instead of HTTPS
• restarted my computer

I am getting this message when trying to push:

Pushing to bitbucket.org:OtherUser/RepositoryName.git
git@bitbucket.org: Permission denied (publickey).
fatal: Could not read from remote repository.

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

I'm stuck and don't know what else to try.

Thanks.

Hi @eyesofjeremy 

On that repository, are you an admin or have write permissions?
