Editing Disabling Expired Certificate on demo.apoyar

Go to demo.apoyar


- Run below command to make backup

•	cp /etc/ca-certificates.conf /etc/ca-certificates.conf.orig



- Run below command to edit the file

•	vi /etc/ca-certificates.conf



- To disable expired certificate in the list, just we have to put exclamation (!) in front of that certificate name and save the file as below


Change “mozilla/DST_Root_CA_X3.crt” in “!mozilla/DST_Root_CA_X3.crt” and save


- Once done, run below command to update

•	update-ca-certificates

This way we can forcefully make ubuntu to use next available certificate in the list.
