How do I solve the certificate error in debian. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

Question

So I am trying to install React on my computer which runs ChromeOS but I am running debian side by side. When I try to execute the command curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - then the error CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none comes and this error is also shown when I run sudo apt-get update. I have tried to do many things but nothing has happened, please help me as this is very important.

In ubuntu:

• Go to /usr/local/share/ca-certificates/
• Create a new folder, i.e. "sudo mkdir school"
• Copy the .crt file into the school folder
• Make sure the permissions are OK (755 for the folder, 644 for the file)
• Run "sudo update-ca-certificates"
