I've been following instructions from the torproject.org to install Tor on Ubuntu Focal Fossa. While running the following code:

wget -qO- https://deb.torproject.org/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc | gpg --dearmor | tee /usr/share/keyrings/tor-archive-keyring.gpg >/dev/null

I got the following error: tee: /usr/share/keyrings/tor-archive-keyring.gpg: Permission denied

Before implementing blindly from the Internet, I decided to ask for support here. Perhaps, someone has already came across such an issue.

Thank you.
