alex@xxxxx:~$ ssh [email protected] PTY allocation request failed on channel 0 Welcome to GitLab, Anonymous! Connection to gitlab.xxx.xx closed.

I tried with 5.4 stable and the same problem on production server.

But when for the sake of interest I installed 5.4 on local test server with virtual box and It works fine. Now I am even had compared everything, but It does not push on production server. Looks like this problem is related to SSH.

I searched already a lot, but all solutions I tried did not work in my case. I have already no idea, feels like it is kind of software bug...

I will appreciate any help. Thanks in advance! Kind regards, Alex

Answer 1

Try also pushing to the https url instead of the ssh this can save you lot of trouble - for example use this:

git remote add origin https://gitlab.com/someuser/algorithm-excercises.git

instead of:

git remote add origin [email protected]:someuser/algorithm-excercises.git

Answer 2

I found this after searching alot. It will work perfectly fine for me.

1. Go to "Git Bash" just like cmd.
2. Type ssh-keygen
3. Press enter.
4. It will ask you to save the key to the specific directory.
5. Press enter. It will prompt you to type password or enter without password.
6. The public key will be created to the specific directory.
7. Now go to the directory and open .ssh folder.
8. You'll see a file id_rsa.pub. Open it on notepad. Copy all text from it.
9. Go to https://gitlab.com/profile/keys .
10. Paste here in the "key" textfield.
11. Now click on the "Title" below. It will automatically get filled.
12. Then click "Add key".

Now give it a shot and it will work for sure.

Answer 3

Hi I had a similar problem (it was after adding new ssh key to a newly created user) I fixed it regenerating authorized_keys which was corrupted

cd /home/git/gitlab

sudo -u git -H bundle exec rake gitlab:shell:setup RAILS_ENV=production
This will rebuild an authorized_keys file.
You will lose any data stored in authorized_keys file.
Do you want to continue (yes/no)? yes

Answer 4

I posted an answer to a similar question

Why does ssh connection to gitlab not work (while http push and clone work fine)?

which involves adding your public key to

/home/git/repositories/.ssh/authorized_keys

Answer 5

open your terminal and make public key:

ssh-keygen -t rsa -C "[email protected]" -b 4096

go to your ssh rsa folder in your system: on Mac go to GO to Folder and type this address:

~/.ssh

then open it with text editor and copy the key

then go to gitlab setting shh key and pate it there https://gitlab.com/profile/keys/2346923

then try again

git push -u origin master

Answer 6

Adding .ssh folder in repositories worked for me so I have done this:

sudo -u git -H ln -s /home/git/.ssh /home/git/repositories/

Now all users can add the key from gitlab web and use ssh.

Answer 7

Make sure you have an existing SSH key pair in local.

Go to your home directory, then go to the .ssh/ subdirectory. If the .ssh/ subdirectory doesn't exist, you are either not in the home directory, or you haven't used ssh before.

If not exist, You need to Generate an SSH key pair in .ssh/ subdirectory:

1. cd ~
2. cd .ssh/
3. ssh-keygen -t ed25519 -C "<comment>"

Then just press enter to finish.
