Tor Browser version check url has been changed by The Tor Project (https://trac.torproject.org/projects/tor/ticket/8940#comment:21).
Please run these two commands.
Then check if whonixcheck and Whonix’s Tor Browser updater are still working for you.
If this works, I plan to write a blog post about this.
The second command returns 0. whonixcheck and Tor Browser updater are still working.
They both should exit 0?
No. The first command modifies “/usr/lib/whonix/whonixcheck/65_check-torbrowser” which does not exist on this side (I believe it was changed in Whonix 8.2.2).
If I run
sudo sed -i "s#https://check.torproject.org/RecommendedTBBVersions#https://www.torproject.org/projects/torbrowser/RecommendedTBBVersions#g" /usr/lib/whonixcheck/check_torbrowser ; echo $?
it returns 0 and whonixcheck is still working.
This is supposed as a stable hotfix for versions 8, 8.1, 8.2, 8.3. As a stopgap until Whonix 9.
