gpg: keyserver receive failed: No route to host stack overflow

Question

While attempting to set up fastlane for my iOS application, I encountered challenges while installing RVM.

My command is

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113************* 7D2BAF1CF37B13E2069D69561*************

Answer 1

Please use

hkp://ipv4.pool.sks-keyservers.net

instead of

hkp://keys.gnupg.net

type this command

gpg --keyserver hkp://ipv4.pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113************* 7D2BAF1CF37B13E2069D69561*************

Answer 2

TL;DR; The list of key servers is unstable and some of them are not pingeable at all. Here's a way of finding an available server

I've tried different key servers and got a

gpg: keyserver receive failed: No route to host or a gpg: keyserver receive failed: Operation timed out

You have to find a server that's up and running correctly

1. Run gpg-connect-agent --dirmngr 'keyserver --hosttable' to get the list of available servers
2. Run the gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C2………………6956105BD0E739499BDB and instead of hkp://pool.sks... try few of the servers URL
