A week ago I was testing 4.1 and got this error trying to download tor browser update in a whonix ws template. Today I also got the same error after a fresh install of 4.0.4. I tried to work around it by updating whonix ws thorough the qubes-dom0-update but the tor browser downloader still gives the error “GPG download signature could NOT be verified” I’m assuming I could manually install a GPG key and will try to do that. I would appreciate if someone might know of an easy fix for this.
I just got an update (thought I had updated it already) and it seems to be working now. I Should have tried to update whonix ws twice.
