Problem with adding gpg while installing Tor browser: Permission denied

Question

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.

You need to run this with root privileges. Add sudo before the tee command. For example:

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

From https://support.torproject.org/apt/tor-deb-repo/

Note: The symbol # refers to running the code as root. This means you should have access to a user account with system administration privileges, e.g your user should be in the sudo group.
