I am always getting the below gpg error message. I have also tried adding a PPA from webupd8 but the result is same. How can I resolve this error?

user@work:~$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0DF731E45CE24F27EEEB1450EFDC8610341D9410

gpg: keyserver receive failed: No keyserver available

user@work:~$ sudo apt-key adv -vv --keyserver hkp://keyserver.ubuntu.com:80/ --recv-keys 0DF731E45CE24F27EEEB1450EFDC8610341D9410

  • Are you behind a proxy or something?

  • Add the output of sudo apt-key adv -vv --keyserver hkp://keyserver.ubuntu.com:80/ --recv-keys 0DF731E45CE24F27EEEB1450EFDC8610341D9410 to the question, please.

  • Did you change /usr/bin/gpg? Usually it doesn't start or require dirmngr, that's an indication that gpg2 is being used.

  • I did not change anything after the install yesterday. I just installed my lubuntu last night and when I will install spotify there is an error like that

  • This is happening on Debian too, freshly installed gpg. Definitely broken out of the box.

I got this error trying to update to Mono 6. I solved it by switching from keyserver.ubuntu.com to keys.gnupg.net in the apt-key command.
