I tried to install the Tor Browser from the official repo.
When trying to launch it says: “Download Tor Browser for the first time”
After a little waiting a error message pops up:
SIGNATURE VERIFICATION FAILED!
Error Code: […]: Key expired
You might be under attack, there might be a network problem or you may be missing a recently added Tor browser Verification key.
Online I found this fix (that didnt work for me: gpg: keyserver refresh failed: No keyserver available): gpg --homedir "$HOME/.local/share/torbrowser/gnupg_homedir/" --refresh-keys --keyserver pgp.mit.edu
I just tried the version 0.3.2-4 version. I get a pop up message during the installation process “the version of Tor browser you have installed is earlier than it should be, which could be a sign of an attack!” I clicked okay, and the installer kept spinning and nothing happened.
I tired the Flatpak version and that works just fine.
I get the same as @fhins 0.3.2-4 doesn’t work and produces the error dialog box mentioned.
I’ve been working fine (don’t run it daily but use it a couple times a week, when I launched it yesterday (October 1st, 2020) it “updated” itself and started producing that error message. I had last run it about a week prior to that and it was working fine.
EDIT- Update
After updating my system (I usually wait a couple days after release) torbrowser is now at 0.3.2-6 and seems to be working fine again. I also just realized this thread was over a month old and should probably be close with @Yochanan post set as the resolution so that in the future while related doesn’t appear to be a current issue. At this time 0.3.2-6 seems to be working correctly and as intended.
