How to add a CA issued by a Windows Certificate Authority to Ubuntu?

Question

linux

There is a root certificate from screw infrastructure. It has the extension .der , but simply renaming it to .pem Chrome for Linux ate it. But Ubuntu still doesn't. Neither through the built-in import (the import button is blocked) nor in / ssl / certs is picked up.

What to do?

Answer 1

openssl x509 -inform der -in certificate.der -out certificate.pem
