I was trying to install GLPK 4.35 on my Ubuntu 12.05 LTS system but  
couldn't succeed. I downloaded the sig file and ran the following  

sudo gpg --verify glpk-4.35.tar.gz.sig

But it showed public key requirements. So I ran the following command:

sudo gpg --keyserver --recv-keys 5981E818

But then it showed following error message:

gpg: WARNING: unsafe ownership on configuration file  
gpg: external program calls are disabled due to unsafe options file  
gpg: keyserver communications error: general error
gpg: keyserver receive failed: general error

In the conf file everything is commented. What should I do know? Your  
help regarding this matter would me much appreciated.

Kind regards
