I have installed ubuntu-20.04-desktop-amd64.iso in Oracle VM VirtualBox. But there are certificate issues . I cannot access any https (e.g. https://www.google.com) using Firefox or Chrome. Similarly curl gives issue. I want to install Kubernetes in this vm. But it is reporting similar error with those distribution sites. I tried installing, and reinstallaing ca-certiicates. It still not working.
This post indicates that BC Unified Agent needs to be disabled. I am unsure how to do that.
After installing the OS(both in general and especially Ubuntu/any Linux) , Do we need to install root certificates separately?
Thanks in advance for any help/pointer.
