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

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.
