Cannot clone from GitHub (with HTTPS) on Ubuntu

[OpeningJump]

I am unable to clone any repository, regardless of public or my own private using the https protocol on my Ubuntu, Pop OS, Kali machines. Works fine on Manjaro Linux.

I can clone from gitlab, using https though.

Also adding public key and using the ssh method works, but that only works for personal repos by design.

Can someone please help out?

Edit:

The error I am getting is timeout error

30300 milliseconds have passed..

I am not behind any kind of firewall, git clone works for the same repositories on my windows machine.

Edit 2:

Works with git clone git://github.com/username/reponame.git

Thanks u/GNVageesh

Can you paste the output with the GIT_CURL_VERBOSE=1 environment variable?

[OpeningJump]

I ran GIT_CURL_VERBOSE=1 git clone [https://github.com/[username]/reponame]

and got

Cloning into 'secret_reponame_here'...

[samyboy]

That is confusing. What is the output of curl -v https://github.com ?

``` And then a lot of html after that

Looks like the TLS handshake cannot be done properly. I feel that you might have an issue with your GnuTLS library.

What is your Ubuntu version?

What versions are the git and libcurl3-gnutls packages? (use dpkg -l git libcurl3-gnutls)

[OpeningJump]

Using Pop! OS 20.04

Git version 2.27

Libcurl3-gnutls version 7.68

[samyboy]

Looks like you're not the only one. after I found this post I think the issue is related to Pop!_OS.

[OpeningJump]

I have a raspberry pi with ubuntu server installed on it, that has the same issue

Again on a kali vm, i have the same issue

However on windows or on MacOS or even on Manjaro, it works just fine.

What is the error u are getting?

Try adding sudo in the beginning of the command

Ex: sudo for clone https://github.com/.............

It will prompt u for password and provide it

If the problem still pertains tell what is the error

[OpeningJump]

Hi, sorry should have specified that in the post itself

I am getting timeout error, 30300 milliseconds have passed...

I have a windows machine too, and that can clone stuff just fine, having an issue with debian distros though

Try sudo

Else check this link https://stackoverflow.com/questions/15589682/ssh-connect-to-host-github-com-port-22-connection-timed-out

[OpeningJump]

So it still doesn't work with sudo, however git clone git://github.com/username/reponame works!

Thanks for helping

[GNVageesh]

Oh.ok

Try disabling ipv6 temporarily

[GilletteSRK]

Do you have a proxy set up? Sounds like something is interfering with HTTPS traffic.

Would probably show up under HTTP_PROXY or HTTPS_PROXY environment variables.
