I'm new to Ubuntu and have a question. My company uses a custom certificate which is put into the certificate chain. Having this, Firefox always asks me to add an exception and also on the terminal I can't use wget for https addresses for example.

Is there any way to make Ubuntu accept / learn to use our company's certificate? I already tried to export the certificate from Firefox to a .crt file, copy it to /usr/local/share/ca-certificates and call update-ca-certificates, but with no success.

Any idea? If you need further information, let me know. Thanks in advance.


Thanks for the comment regarding FF. Anyhow I need to solve this for the command line interface too. By the way, this is the error I get in the command line. 192.168.1.8:1357 is my “local” proxy, which communicates with the company’s Windows Proxy.

    This seems to show a correct method (2 bounties awared) for FF and has a mention of FF using its own database: askubuntu.com/questions/244582/… In the generic one there is this comment about FF too: askubuntu.com/questions/73287/… – Rinzwind Oct 14 '15 at 14:59
  • First, thanks for your comment. I could fix the issue for FF now. I've edited my initial post, since my problem is not FF related only. But thanks for your hints regarding FF. – Kenshin Oct 15 '15 at 5:35
