Yes, deb.torproject.org is also served through via an Onion Service: http://apow7mjfryruh65chtdydfmqfpj5btws7nbocgtaovhvezgccyjazpqd.onion/

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.

如需通过 Tor 使用apt，需要安装 apt 运载工具。

   ‪# apt install apt-transport-tor

Then you need to add the following entries to /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/:

   # 对于稳定版本。
   deb tor://apow7mjfryruh65chtdydfmqfpj5btws7nbocgtaovhvezgccyjazpqd.onion/torproject.org <DISTRIBUTION> main

   # 对于不稳定版本。
   deb tor://apow7mjfryruh65chtdydfmqfpj5btws7nbocgtaovhvezgccyjazpqd.onion/torproject.org tor-nightly-master-<DISTRIBUTION> main

Replace <DISTRIBUTION> with your Operating System codename. Run lsb_release -c or cat /etc/debian_version to check the Operating System version.

Now refresh your sources and try to install tor again:

   ‪# apt update
   ‪# apt install tor
