OpenSSL certs on OLD Debian

Problem: (Outdated SSL on Debian Squeeze, Wheezy, Jessie, Stretch etc):

error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

Solution: Copy /etc/ssl/certs from newer Debian installation:

## make backup copy:
mkdir -p /backup
rsync -avP /etc /backup/`date +%d%m%y-%s`

## replace with new certs:
rsync -avP root@NEW-DEBIAN-HOST:/etc/ssl/certs /etc/ssl/
