Thanks for reminding me that. Here is the solution.
Move up to the parent directory of the repository you are trying to download the rpm file from. There will be a public key there, which on opening will give a text file. Save that file on your machine like mykey.txt.
Then, type the following to import the key:
gpg --import mykey.txt
Then try installing the package. The installation will complete successfully.
I have solved this problem. Thanks.
I am very new to Linux and CentOS. I am trying to install a package, vnc-ltsp-cong*.rpm. I tried downloading a lot of versions of it. But from whichever site I may download, I get the same error.
What does this mean? How should I resolve this? how can I install this public key?
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 217521f6
Public key for vnc-ltsp-config-4.0-4.el5.noarch.rpm is not installed
Thanks for any help
