Got a new certificate, but wget and curl are not connecting anymore:

wget https://MYDOMAIN

ERROR: cannot verify MYDOMAINS's certificate, issued by ‘/C=US/O=GeoTrust Inc./OU=Domain Validated SSL/CN=GeoTrust DV SSL CA - G4’:

Checking shows only these files:

ls /etc/ssl/certs/GeoTrust_*

GeoTrust_Global_CA_2.pem                           GeoTrust_Global_CA.pem                             GeoTrust_Primary_Certification_Authority_-_G2.pem  GeoTrust_Primary_Certification_Authority_-_G3.pem

Do I need to wait for ubuntu to add the G4 certificate? Copying files myself sounds scary.

I already did the update-ca-certificates --fresh



 update-ca-certificates --fresh

is only useful if you previously copied the certificate to /usr/local/share/ca-certificates.


  1. download the .pem file you need. (Here is the official download).
  2. copy the file over from your download location to /usr/local/share/ca-certificates using sudo but with the extension .crt. Example command (use the actual name instead of "filename"):

    sudo cp ~/Downloads/filename.pem /usr/local/share/ca-certificates/filename.crt

  3. run update-ca-certificates.

    yeah, but geotrust does not offer it, only the ssl-tools page, so not sure it is a valid one :( Jun 4 '15 at 12:06
  • The 2nd link seems to correct name. And the txt file version seems valid.

  • still could be a scam, why would some random homepage already have the certificate when the company itself is not yet publishing it .. should maybe be moved to sceptics :) Jun 4 '15 at 13:45
  • Just got a reply from geotrust that it's valid, download link here: knowledge.geotrust.com/support/knowledge-base/… Jun 4 '15 at 14:48
  • Oh that is pretty cool from them :D Ill edit the link into the q. Thanks for the rep :D
