 #### WORKAROUND: dependency

 Some ubuntu systems do not have GPG by default. Wire assumes this is already present. Ensure you have gpg installed on all of your nodes before continuing to the next step.
 
+You can check if gpg is installed by running:
+
+```
+gpg --version
+```
+
+Which should produce an output ressembling:
+
+```
+demo@assethost:~$ gpg --version
