    Re: Update error: Cannot verify issuers authority: Certificate

    Looks like the site was missing one of it's intermediate certificates. I've been on https://redirector.gvt1.com and it shows a valid certificate. Is it working now?
    What is the output of
    Code:
    lsb_release -a; uname -a
    Thanks

    Code:
    --no-check-certificate
    option as stated in your output
