Unable to run TOR from terminal (Ubuntu)

Question

When I try to run TOR from the terminal, this message appears:

Jun 01 00:17:19.354 [notice] Tor 0.3.2.10 (git-0edaa32732ec8930) running on Linux with Libevent 2.1.8-stable, OpenSSL 1.1.0g, Zlib 1.2.11, Liblzma 5.2.2, and Libzstd 1.3.3.

TOR is not running, and I have no idea how to solve this. Works perfectly if opened outside the terminal, though. I just want to understand why this is happening.

Answer 1

It seems that TOR is already running. Try to check tor status by running following command in terminal:

sudo service tor status

If it returns "tor is running", then tor is running.

Other possibilities:

1- try to start tor as super user

2- try to provide another config file
