CAcert

CAcert is a free (gratis, free of charge) root certificate trusted by many sites and many distributions and programs. There has been talk about inclusion in ubuntu in 2005 in an UbuntuDownUnder BoF. Yet, sadly this has not happened so far.

Procedure

You can manually install the CAcert root certificate with the following command:

sudo apt-get install ca-certificates

Then you can activate it in firefox with this command:

firefox /usr/share/ca-certificates/cacert.org/*.crt

If you are still getting a message like You have not chosen to trust "Thwate Premium Server CA" you will need to manually copy the SSL Certificate to the ICAClinet directory.

  1. Go into Firefox → Edit → Preferences → Advanced → View Certificates → Authorities Tab
  2. Find the missing certificate, e.g. Thwate Premium Server CA
  3. Export this Certificate to your hard drive somewhere
  4. Run the following command (assuming you Exported to your Downloads directory) to copy the file to the ICAClient directory:

    cp ~/Downloads/ThawtePremiumServerCA /usr/lib/ICAClient/keystore/cacerts
