Debian Repository

Yes, deb.torproject.org is also served through via an Onion Service: http://sdscoq7snqtznauu.onion/

To use Apt over Tor, the apt transport needs to be installed:

   # apt install apt-transport-tor

Then replace the address in the lines added before with, for example:

   # For the stable version.
   deb tor://sdscoq7snqtznauu.onion/torproject.org <DISTRIBUTION> main

   # For the unstable version.
   deb tor://sdscoq7snqtznauu.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 discover.

Now refresh your sources and try if it's still possible to install tor:

   # apt update
   # apt install tor

No. Do not use the packages in Ubuntu's universe. In the past they have not reliably been updated. That means you could be missing stability and security fixes. Please, use Tor Debian repository.

The Tor Project maintains its own Debian package repository. Since Debian provides the LTS version of Tor that this might not always give you the latest stable Tor version, it's recommended to install tor from our repository.

Here's how you can enable Tor Package Repository in Debian based distributions:

1. Install apt-transport-https

To enable all package managers using the libapt-pkg library to access metadata and packages available in sources accessible over https (Hypertext Transfer Protocol Secure).

   # apt install apt-transport-https

2. Add the following entries to /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/

   deb https://deb.torproject.org/torproject.org <DISTRIBUTION> main
   deb-src https://deb.torproject.org/torproject.org <DISTRIBUTION> main

If you want to try experimental packages:

   deb https://deb.torproject.org/torproject.org tor-experimental-0.3.4.x-<DISTRIBUTION> main
   deb-src https://deb.torproject.org/torproject.org tor-experimental-0.3.4.x-<DISTRIBUTION> main

Or nightly builds:

   deb https://deb.torproject.org/torproject.org tor-nightly-master-<DISTRIBUTION> main
   deb-src https://deb.torproject.org/torproject.org tor-nightly-master-<DISTRIBUTION> main

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

3. Then add the gpg key used to sign the packages by running the following commands at your command prompt

   # wget -qO- https://deb.torproject.org/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc | gpg --import
   # gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add -

4. Install tor and tor debian keyring

We provide a Debian package to help you keep our signing key current. It is recommended you use it. Install it with the following commands:

   # apt update
   # apt install tor deb.torproject.org-keyring
