Unable to install nvm on WSL due to network issues

Question

I'm trying to install nvm using curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash on WSL2, but I'm getting different errors. Initially, the curl command would return the following:

> $ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash                                        
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:09 --:--:--     0curl: (6) Could not resolve host: raw.githubusercontent.com

After running netsh int ip reset in Windows, which was suggested in another question, the same command started timing instead:

> $ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash                                        
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:04:59 --:--:--     0
curl: (28) Connection timed out after 300000 milliseconds

I've also tried manually saving the install.sh to my machine and running it locally (after setting its permissions with chmod +x install.sh), but that returns a similar error:

> $ ./install.sh

Failed to clone nvm repo. Please report this!

I can successfully ping github.com. ping -c 100 github.com returns the following:

--- github.com ping statistics ---

This issue suggests that a Windows update resolved the issue, but that's not an option for me since it's a work machine and I can't update beyond build 18363.2039. I've also checked that my VPN is not enabled and I set my DNS to 8.8.8.8 and 8.8.4.4, which had no effect.

Answer 1

Please try the following in your WSL

sudo rm /etc/resolv.conf
sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
sudo bash -c 'echo "[network]" > /etc/wsl.conf'
sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'
sudo chattr +i /etc/resolv.conf

I can install with curl.
