Parent is shutting down, bye...
What is the full command you're using?
Also an alternative (and workaround) to maintain TBB:
sudo apt install torbrowser-launcher
sudo firecfg #optional
torbrowser-launcher #prepend "firejail" if you didn't run previous command
firejail ./start-tor-browser.desktop
:-1:
@SemiIngSoft have you tried using torbrowser-launcher program instead? It handles everything including GPG verification.
@SemiIngSoft Where is your start-tor-browser.desktop?
@SemiIngSoft still an issue?
Closing due to no activity. @SemiIngSoft, please feel free to re-open if you have more info.
