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.
