I've been trying to install a package from a PPA for some hours now. I am running a freshly installed version of ubuntu 14.04.
I've been following these instructions:
https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu
On issuing this command:
sudo add-apt-repository ppa:ethereum/ethereum
I get five errors of this kind: (all of them added to the bottom of the post for reference.)
Traceback (most recent call last):

softwareproperties.ppa.PPAException: 'Error reading https://launchpad.net/api/1.0/~ethereum: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)'
I would think that this has something to do with this line:
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)'
I've tried reinstalling and updating the ca-certificates. And I have run apt-get update and upgrade. (I also tried 15.04 but same results)
Do I have to add/generate a certificate for this particular host?
Any ideas what I might be missing here?
Thankful for any help!

Best Answer
There are a couple things you can try. First off, have you tried creating a new
ethereum-ethereum-<version>.list
file for ethereum in/etc/apt/sources.list.d/
manually? I doubt that will make any difference if it's truly a verifcation error, but if apt is just being screwy that could do it. The line you would want to put in that file is something like:Another thing you could try is, if you trust ethereum, you can pass in the
allow-unauthenticated
flag to apt-get, that may do it. This is NOT a particularly good idea.You could also try and download a certificate from ethereum, but a cursory glance at their blog suggests they're not too hot on signing authorities, so I don't know if that approach is viable.
