Can't push to bitbucket, Permission denied (publickey) - ssh

Question

I am trying to push my project onto my bitbucket, been messing with this for about 4 days pouring through countless problem solving/pages/troubleshooting/tutorials. Im at a loss and very frustrated. I have done this before but on different computers...anyway here is the code/response that I'm getting
~/dev/sample_app git push -u origin --all
The authenticity of host 'bitbucket.org (131.103.20.168)' can't be established.
RSA key fingerprint is 81:7b:2c:f5:6f:18:2b:7c:4b:ec:aa:46:46:74:7c:40.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
~/dev/sample_app
I am on a mac running 10.8.4.
So a little progress has been made, initially there was no .ssh folder so I created that way back in the beginning, there was no known_hosts file so I ran
ssh -T git#bitbucket.org
I chose yes and this created a known_hosts file and when I tried to push again I got:
~/dev/sample_app git push -u origin --all
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
My .ssh folder is 700 and the keys inside are all 600.

Answer 1

You can set IdentityFile flag file in ~/.ssh/config file as follows:
Host bitbucket.org
IdentityFile ~/.ssh/id_rsa
When you run
ssh git#bitbucket.org
the ssh client allows you to selects a file from which the identity (private key) for RSA or DSA authentication is read.
SSH Client To Use Given Private Key ( identity file )

Answer 2

You might be using ssh as the git origin url. Try removing the ssh origin like so
git remote rm origin
Then add new origin with HTTPS url and try pushing again.
git remote add origin https://git#bitbucket.org/SOMETHING/SOMETHING.git
git push -u origin master
Make sure you paste your url from bitbucket as origin.

Answer 3

In my case on fresh Ubuntu 16 machine I was missing files in ~/.ssh folder so what worked:
Go to folder ~/.ssh
Run ssh-keygen and name your file i.e. id_rsa
Run cat ~/.ssh/id_rsa.pub | xclip -sel clip
If you miss xclip just apt-get install xclip :)
Go to (in url change USERNAME to your bitbucket username:) ) https://bitbucket.org/account/user/USERNAME/ssh-keys/
Click Add key and paste the key from the clipboard
Magic - it works now :)

Answer 4

Edit: As Dan Swain points out in the comments, from 1 March 2022 this answer will have been superseded by authentication policy changes: https://bitbucket.org/blog/deprecating-atlassian-account-password-for-bitbucket-api-and-git-activity
The same applies to Github repositories as well, FWIW.
Thanks for the heads-up, Dan.
It might make sysadmins recoil in horror, but after suffering this problem (Windows) I gave up on SSH and went back to HTTPS.
When first adding the remote repository to Git, replace the SSH reference 'git#bitbucket.org...' with the HTTPS URL 'https://<username>#bitbucket.org'.
You have to type your password in every time but, particularly under Windows where SSH is not as commonly available as with the *nix family, I see this as a minor inconvenience compared with the headaches of SSH.

Answer 5

After setting up git with git config --global user.name "My Name" and
git config --global user.email myemail#x.com, I was still having trouble with the Permission Denied, (publickey) error. To solve this, I first generated a new ssh token with
ssh-keygen
and copied it with
pbcopy < ~/.ssh/YOUR_KEY
After that, I went to bitbucket.com to add it as a new SSH key in my settings. Then, I returned to my terminal to add the new key with
ssh-add ~/.ssh/YOUR_KEY.
The big problem that I was having was that I missed the critical ssh-add [key] command.

Answer 6

I had similar problem with BitBucket. in my case, it only fixed after I found out I should remove sudo from git clone command!
According to Attlassian:
You shouldn't use sudo when cloning, pushing, or pulling because the
ssh-agent runs on the user level, not the root level.

Answer 7

A more sustainable solution is to edit .bashrc (e.g. vi ~/.bashrc) and then add the following line to it (replace the key name):
KEY="$HOME/.ssh/YOUR_KEY"
if [ -e "${KEY}" ]; then
ssh-add -q "${KEY}"
fi
This will load the key automatically when you start the shell

Answer 8

If you're using Fedora 33+ and using the RSA algorithm. Use more secure alogrithm like ECDSA or ED25519 instead:
ssh-keygen -t ed25519 -C "your_email#example.com"
Check out the bitbucket support for more details
Cause
The RSA algorithm is being quickly deprecated across operating systems and SSH clients because of various security vulnerabilities, with many of these technologies now outright denying the use of this algorithm.
(info) For example - here is the announcement from OpenSSH regarding
their upcoming deprecation of the ssh-rsa algorithm. In the event that
you are using an operating system or SSH client whose version has this
algorithm disabled, it's possible that any SSH keys previously
generated using this algorithm will no longer be accepted by these
technologies.
Resolution
To fully resolve this issue, our team recommends that these deprecated
keys be re-generated using a supported and more secure algorithm such
as ECDSA and ED25519

Answer 9

I faced same issues in Linux (Ubuntu).
I solved it using setup in git:
git config --global user.name "Your Name"
git config --global user.email your.email#example.com
Printing the public key using cat and SSH key to bitbucket.org:
$ cat ~/.ssh/id_rsa.pub
Adding Bitbucket and pushing up the repository:
git remote add origin git#bitbucket.org:<username>/your repository name.git
git push -u origin --all
That's all!

Answer 10

In my case, this issue happened because I had a number of ssh keys in the ~/.ssh. I had to create a bitbucket.org specific entry in ~/.ssh/config as follows:
Host bitbucket.org
Hostname bitbucket.org
IdentityFile <location-of-.ssh-directory>/bb-rsa
IdentitiesOnly=yes
My guess is that since we don't specify a key while cloning, ssh tries all the keys in ~/.ssh which bitbucket thinks as a hacking attempt and rejects our repo clone attempt.

Answer 11

In my case it solved the problem to add the ssh key from the directory
~/.ssh/id_rsa.pub
on bitbucket.org. I named it also id_rsa.pub on the website.
At the beginning I added another key I created just for bitbucket and named it like that. The first remote actions worked but after some days the request have been denied.

Answer 12

Check for exisiting SSH Key
ls -al ~/.ssh
Copy the SSH Key
cat ~/.ssh/id_rsa.pub | pbcopy
Add the copied SSH Key to 'Bitbucket Settings', 'Security', 'SSH Keys'.

Answer 13

If you have multiple keys in your computer make sure you add bitbucket to the list such as below in
.ssh/config
# Company account
Host company
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_accelya
# Personal account
Host personal
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_personal
# Personal account bitbucket
Host bitbucket
HostName bitbucket.org
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_personal_bitbucket

Answer 14

This may be obvious, but I spent quite a bit of time on it.
Check the destination when running git remote -v
In my case I had the ssh keys perfectly set up but the output from this command was:
origin get#github.com:USERNAME/REPOSITORY.git
(notice the get not git)
and not
origin git#github.com:USERNAME/REPOSITORY.git
Again, this was a very particular case, but be sure to check the strings carefully of this system if you're having trouble.
You can fix this with the following commands:
git remote set-url origin git#github.com:USERNAME/REPOSITORY.git

Answer 15

Make sure your have switched to the correct user on terminal.
In my case root user was not the one which has ssh keys added at the bitbucket settings panel. Running git with sudo makes it run from root user and my own user was the one who has keys added.

Answer 16

In my case my issue was that I tried using the .ppk file the putty generated and no matter what I tried nothing worked.
In the end I figured that the it was the wrong file and I had to export it, save it as the id_rsa file and load it, then everything worked.

Answer 17

If any.ssh fix didn't work or you cloned as https there can be a validation issue. in my case, I fixed this error by providing my username and password when cloning the repo. This issue can occur when you are using multiple accounts in a same machine.
use "git clone https://username:password#github.com/username/repository.git" command with your user name and password and repo URL.

Answer 18

I like the Answers here, but they all kind of miss a possible root cause.
with the command:
ssh -T git#bitbucket.org
replace bitbucket.org with your own bitbucket host.
If you get an answer like:
This deploy key has read access to the following repositories:
team-name/repository-name
that is why pushing to the repository is not working.
This you can also double check in the Bitbucket Web UI, notice the read-only access in the description:
Hope this gives a different perspective to the same problem.

Answer 19

I update config file with the top line to get it working
PubkeyAcceptedKeyTypes +ssh-rsa
Host <yourhost>
IdentityFile ~/.ssh/id_rsa

Answer 20

My Solution:
git remote rm origin
Add you user name before #bitbucket.org to the repo URL
git remote add origin https://{USER_NAME}#bitbucket.org/{NAME}/{REPO_NAME}.git
git push -u origin master

Answer 21

In Windows, #efesaid answer worked for solving issues with the ssh connection test. By the way, you can add a -v to see what keys (by name) are being attempted and why the connection fails.
However, when pushing to bitbucket, using git#bitbucket.org:user/repo.git, it seems that the host is not precisely bitbucket.org so I still was getting permission denied problems. I solved them by (re)naming my key to id_rsa (this is the key name that was being attempted in the ssh test).
This works if you have a single rsa key. For multiple keys, perhaps the host in the config file must be
bitbucket.org:username
but I am no sure this is unde

Answer 22

I think that the bitbucket instructions are best. Check if ssh is installed and if not install it

get this key and add it as key in the bitbucket settings

Answer 23

I got round a similar issue where I had previously used HTTPS to access the repository and had to switch to SSH by setting the url like so;
git remote set-url origin ssh://git#bitbucket.org/...

Answer 24

My problem was to do with permissions.
My project directory was owned by root, but I was logged in as ubuntu. I would get PERMISSION DENIED if I typed in a git command, e.g. git pull origin master, so I used sudo git pull origin master.
I had registered ubuntu's SSH key from /home/ubuntu/.ssh/id_rsa.pub with BitBucket.
However, I was using sudo. So the SSH key used was actually /home/root/.ssh/id_rsa.pub which was different to what BitBucket had.
Solution for my case
chown -R username_here:username_here project/folder/here
Now it should work if you don't prepend sudo
OR give BitBucket root's key

Answer 25

In source tree select your project right click then you find an option "Convert to SSH"-> Repair -> login this solved for me

Answer 26

If you are using SourceTree with Bitbucket, the solution is the next:
Go to your personal Bitbucket settings
Got to App passwords and create an app password
Give the next permissions to the app password:
Repositories (R-W-A-D)
Projects (R-W)
Pull request (R-W)
After that, keep the password generated
Try to clone again your repo
A password popup will be displayed, input the generated password.
That's all.
