Hi @CHEN TZEN KOK and welcome to the community!

If the SSH keys still exist in the ~/.ssh directory on your machine and nothing has changed with regards to their permissions, you can add the following to the ~/.ssh/config file on oyur machine

Host bitbucket.org
    AddKeysToAgent yes
    IdentityFile ~/.ssh/id_rsa
    IdentitiesOnly yes

where id_rsa, replace with the name of the private key, whose public key you have uploaded to Bitbucket. This assumes that the SSH key pair exists in the ~/.ssh directory of your machine.

If there is no file named config in your ~/.ssh directory, you can create a new file with this name and add to it the content I shared above. This will ensure that this specific SSH key will be offered when you clone/pull/push to a Bitbucket Cloud repo via SSH.

Please feel free to let us know how it goes.

Kind regards,
Theodora

Hi @CHEN TZEN KOK

Welcome to the Atlassian Community.

Could it be that you're ssh keys on your machine have been moved, deleted, or had their permission changed?
Looking at the error messages it seems that your git is not able to find any of your public ssh keys on your local machine.

Cheers,
Peter
