Also 'command -v nvm' returns nothing

What did you expect to happen?

Successful installation

Is there anything in any of your profile files that modifies the PATH?

No, .bashrc exists but PATH is not modified inside it

If you are having installation issues, or getting "N/A", what does curl -I --compressed -v https://nodejs.org/dist/ print out?

Are you using WSL? nvm doesn’t work on windows otherwise.

[ljharb]

Ah, i see in the title you are. In that case, what happens if you try to use git to clone this repo directly?

[Sparrownor1]

Similar output Cloning into 'nvm'... fatal: unable to access 'https://github.com/nvm-sh/nvm/': Could not resolve host: github.com

[ljharb]

This implies your computer can’t reach GitHub. What happens if you run curl -I --compressed -v https://github.com/nvm-sh/nvm ?

[Sparrownor1]

That is kind of spooky but I cannot fathom as to why that would be the case. What could I do to fix it?

* Could not resolve host: github.com
* Closing connection 0
curl: (6) Could not resolve host: github.com

Since i assume you’re accessing this page itself on the same machine, do you have any proxy settings set up in your web browser that the OS might lack?

[ljharb]

One possibility is that you have ipv6 enabled. Could you try disabling it?

I reset my laptop today, and installed stock Chrome. I have not made any changes to any proxy settings to I suppose everything is still default.

One possibility is that you have ipv6 enabled. Could you try disabling it?

Attempting to right now

[Sparrownor1]

Disabled ipv6 but still the same output

EDIT: also if it helps I am able to ping google.com but not ping github.com Error says Temporary failure in name resolution

[ljharb]

Try setting your dns servers to 8.8.8.8 or 1.1.1.1

I think I’ll close this as a duplicate of #2392 - hopefully something in there is helpful.

in general, there’s nothing nvm can do if your command line can’t connect to github :-/

[Sparrownor1]

Here is the output from the curl -I stuff, it is different now. Posting this as the other thread had a 404 error but mine is 200

Not an elegant solution but I uninstalled Ubuntu and after redownloading everything works fine

[ljharb]

Glad to hear it’s working! Sorry i wasn’t able to help find an easier solution.
