Hello all, I have been running FreedomBox successfully now with a few of the apps. I’m trying to add Tor and it is erroring out. Can anyone help with the following?
Problem Description
I am installing Tor through the Freedombox Apps dashboard but it errors out.
Steps to Reproduce
N/A - clicking Tor install
Expected Results
Clean install
Actual results
I get an error with the following message:
Error installing application: (‘tor’, ‘’, ‘Traceback (most recent call last):\n File “/usr/share/plinth/actions/tor”, line 538, in \n main()\n File “/usr/share/plinth/actions/tor”, line 534, in main\n subcommand_method(arguments)\n File “/usr/share/plinth/actions/tor”, line 72, in subcommand_setup\n _first_time_setup()\n File “/usr/share/plinth/actions/tor”, line 79, in _first_time_setup\n _disable_apt_transport_tor()\n File “/usr/share/plinth/actions/tor”, line 467, in _disable_apt_transport_tor\n for uri_path in iter_apt_uris(aug):\nUnboundLocalError: local variable 'aug' referenced before assignment\n’)
Information
FreedomBox version: You are running Raspbian GNU/Linux 11 (bullseye) and FreedomBox version 21.4.4. FreedomBox is up to date.
Hardware: Rasperry Pi B+
How did you install FreedomBox?: I’ve forgotten now, it was by CLI or an image. Freedombox is working successfully with TT-RSS and Radicale and in general.
+1 for this error; I attempted to install the Tor app this evening and encountered the same issue.

“local variable 'aug'” has some backslashes that Discourse is interpreting as markdown and removing from the error message, see the screenshot:
I opened the referenced file /usr/share/plinth/actions/tor and looked at a few of the lines noted in the error message, but I honestly have no idea what I’m looking at. If there is a typo or something in there I would have no idea.
I rebooted the box but it did not change the result.
Information
Debian 11, FreedomBox version 22.15
Hardware
Olimex A20-OLinuXino-LIME2 board
How did you install FreedomBox?
Pre-installed version.
@ntfz I’m not sure if you saw it, but Sunil replied in the issue Benedek opened (in the link above), saying:
This failure to create augeas instances happens under two conditions:
When the new Deb822 format sources files are present: /etc/apt/sources.list.d/*.sources . These files are not yet understood.
When there are errors parsing the old format files: /etc/apt/sources.list or /etc/apt/sources.list.d/*.list
I took a peek in /etc/apt/sources.list.d and /etc/apt/sources on my box and did not see any .sources files at all–I think probably I do not have any of the “new Deb822 format sources files” Sunil mentioned.
I took a look through the .list files, thinking maybe I could spot something odd that is causing the parsing error Sunil referenced; the only thing that stood out to me was my tailscale.list file that looks like this:
# Tailscale packages for debian bullseye
deb [signed-by=/usr/share/keyrings/tailscale-archive-keyring.gpg] https://pkgs.tailscale.com/stable/debian bullseye main
The second line looks a bit clunkier than the other .list files I have, so I took a guess and commented it out. After commenting out the line, I was able to install the Tor app!
I uncommented the line afterward and ran a normal sudo apt update && sudo apt upgrade with no issues. Tailscale and Tor are both up and appear to be working fine so it may have just been a hiccup with how the app gets installed.
Thanks @BluishHumility! That precisely points the problem. This is an issue in augeus lens that we are using to parse the sources file. I shall report this issue to them and try to fix it.
Thanks for breaking the technical component down for me @BluishHumility. I will try this and report back, I suspect it will work for me, too. And thank you Sunil for providing the specifics!
I checked in on my /etc/apt/sources.list and /etc/apt/sources.list.d
In the latter I only had a docker.list and raspi.list. I tried commenting out each of their lines (each had one) and got the same parsing error.
The former has just one item:
deb Index of /raspbian bullseye main contrib non-free rpi
[I tried commenting that out, too, but the install failed for different reasons]
Those had not fixed the issue with installing Tor, in my case. I did not have the Tailscale item in my list to comment out.
