+## Troubleshooting
+### Forgejo GPG verification failure
+If you are trying to verify a gpg key on Forgejo and it keeps failing it may be because your key has more than one subkey.  
+The solution is:  
+
+01. Make a backup of your gpg key.  
+02. Delete all but one subkey
+    * This key must be a signing key
+03. Run the command Forgejo gives ye
+04. Restore the original key (if ye desire)
