Answer 1

Make sure that you have ssh installed.

Ubuntu: sudo apt-get install ssh

Answer 2

I had the same issue on Xubuntu. Doing ssh -Tv git@github.com hangs forever. Disabling the firewall with sudo ufw disable solved the problem.

Answer 3

Try using HTTPS instead of SSH. Port 22 might be blocked by a firewall.

E.g. instead of:

git clone git@bitbucket.org:repo-owner/my-project.git

Connect via HTTPS:

git clone https://username@bitbucket.org/repo-owner/my-project.git

Answer 4

GitHub offers a few different ways to connect to the remote repo. I am behind an onerous firewall. All methods also hang except using http (not https).

For example, the JavaHamcrest project offers (anonymously):

• https://github.com/hamcrest/JavaHamcrest.git
• git@github.com:hamcrest/JavaHamcrest.git
• git://github.com/hamcrest/JavaHamcrest.git

You may also try:

• http://github.com/hamcrest/JavaHamcrest.git

Finally, prefix your UNIX command with GIT_TRACE=1 and GIT_CURL_VERBOSE=1, and use Git option --verbose for maximum debug output.

Example: GIT_TRACE=1 GIT_CURL_VERBOSE=1 git clone --verbose http://github.com/hamcrest/JavaHamcrest.git

Answer 5

In my case I found that my Anti-Virus was blocking access to Github. The popup appeared behind all my windows which I did not realize earlier. The moment I allowed access to GitHub "ssh -vT git@github.com" command worked. I was also able to clone a repository and push my code from local to Github.

Answer 6

Was having the same issue on Windows / msys2. Seems to be something with the router. I pinged github.com and then cloned using my username

git clone https://cchamberlain@github.com/cchamberlain/<repo>

and it worked. Not sure if its a one-off yet.
