I'm trying to install bitcoind by simply doing sudo apt-get install bitcoind
, but I get this error saying that the following packages could not be authenticated:
libdb5.1++ libcrypto++9 bitcoind
I can simply install them without authenticating them, but since this program may handle money, I would like them to be the correct ones. So I found this solution here on AskUbuntu, which suggests to do the following:
$ sudo apt-key update
$ sudo apt-get update
After the first command, it lists four keys of which it says that all remain unchanged. The second command simply does the usual, but it ends with a message saying that there was a GPG-error. After some blabla, it then says that the following signatures are invalid (freely translated from Dutch):
BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key <[email protected]>
BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]>
And the following signatures could not be verified because the public key is not available:
NO_PUBKEY 1F968B3903D886E7
And the following sugnatures were invalid:
BADSIG E585066A30C18A2B Opera Software Archive Automatic Signing Key 2013 <[email protected]>
And that getting stuff from the following address has failed:
http://extras.ubuntu.com/ubuntu/dists/precise/Release
Does anybody know what I can do to solve this?
sudo apt-key update && sudo apt-get update
?
