Public bug reported: I am not able to start tor browser since a couple of days because gpg loops refreshing keys. Killing gpg allows tor browser to start:

See https://gist.github.com/rjhansen/67ab921ffb4084c865b3618d6955275f for description of DoS on key servers which seems to be the reason. Key server is hard coded in torbrowser-launcher. It needs to either be changed or made configurable.
