Today I tried executed the command: apt-get update. But there seems to be a problem, because I get error-messages like these:
Err https://mirror.umd.edu trusty/main Sources
server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
Err https://mirror.umd.edu trusty/restricted Sources
server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
etc. And then:
W: Failed to fetch https://mirror.umd.edu/ubuntu/dists/trusty/main/source/Sources server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
W: Failed to fetch https://mirror.umd.edu/ubuntu/dists/trusty/restricted/source/Sources server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
etc.
I guess this problem is because I don't have a file called 'ca-certificates.crt' in that folder. I looked also on another server with Ubuntu 14.04 on it, but this certicate file doesn't excist there either. So, where can I find/download this crt-file?
I hope someone can help me.
Thanks, Kevin
