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

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
