Cannot push using git on linux

[Gleb Kartashov]

Steps I've taken:

Follow this guide exactly https://support.atlassian.com/bitbucket-cloud/docs/set-up-an-ssh-key/

This is my test connection message:

ssh -T git@bitbucket.org
authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled

 This is message I get when I try to push my files into my repo

root@jirau-virtual-machine:/var/atlassian/application-data/jira/scripts# git push bitbucket2
root@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.

 This repo does exist in my Bitbucket Cloud and was created by me

My remote settings:

root@jirau-virtual-machine:/var/atlassian/application-data/jira/scripts# git remote -v
bitbucket2 ssh://bitbucket.org/inforcekz_jira/scripts/src/master/ (fetch)
bitbucket2 ssh://bitbucket.org/inforcekz_jira/scripts/src/master/ (push)

SSH settings under Personal settings in Bitbucket:

SSH port is open on my VM as I can only connect to it via SSH

I've got the same issue, but I found better solution, I just changed remote from git@bitbucket.org into user@bitbucket.org

Hey Gleb,

Welcome to the Bitbucket Cloud Community!

A common issue I see is that the SSH will authenticate, but it will not use the correct key and therefore will fail to grant access.
Please try to update your remote URL as follows to specify the username to authenticate with in GIT, provided your ~/.ssh/config file has been mapped correctly this should authenticate without issues:

git remote set-url origin username@bitbucket.org:workspaceID/reposlug.git

If this does not work, try to edit your config file directly to, again, specify the username that you would be using to authenticate with - replacing "username" in the text below:

#username account

Host bitbucket.org-username

HostName bitbucket.org

User git

IdentityFile ~/.ssh/privatekeyname

IdentitiesOnly yes

Hope this helps.

Cheers!
