gpg: no valid OpenPGP data found

Question

I am trying to install Jenkins on Ubuntu 13.10 and I am getting the above mentioned error when i try to run the following command:

wget -q -O - http://pkg.je         


        

Answer 1

I got this error in an Ubuntu Docker container. I believe the cause was that the container was missing CA certs. To fix it, I had to run:

apt-get update
apt-get install ca-certificates

Answer 2

By executing the following command, it will save a jenkins-ci.org.key file in the current working directory:

curl -O http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key

Then use the following command to add the key file:

apt-key add jenkins-ci.org.key

If the system returns OK, then the key file has been successfully added.

Answer 3

In my case, the problem turned out to be that the keyfile was behind a 301 Moved Permanently redirect, which the curl command failed to follow. I fixed it by using wget instead:

wget URL
sudo apt-key add FILENAME

...where FILENAME is the file name that wget outputs after it downloads the file.

Update: Alternatively, you can use curl -L to make curl follow redirects.

Answer 4

I also got the same error. I've referred to the below mentioned link and ran this commands

gpg --import fails with no valid OpenPGP data found

gpg --import KEYS
sudo apt-get update

It worked.

I'm using Ubuntu version 12.04

Answer 5

This problem might occur if you are behind corporate proxy and corporation uses its own certificate. Just add "--no-check-certificate" in the command. e.g. wget --no-check-certificate -qO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

It works. If you want to see what is going on, you can use verbose command instead of quiet before adding "--no-check-certificate" option. e.g. wget -vO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add - This will tell you to use "--no-check-certificate" if you are behind proxy.

Answer 6
