Answer by Gerhard Burger for nvm ls-remote command results in "N/A"

Most likely this is caused by curl not being able to use certificates for https urls (verify with curl $NVM_NODEJS_ORG_MIRROR). Instead of using the http url as workaround, it is IMO much better to fix curl.

Assuming you have the ca-certificates package installed, add the following line to your .bashrc (source1, source2):

export CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
