Could not resolve ''

I’m following the instructions to install Sphinx described here:

After running command:

sudo apt update

I get the following error: “Could not resolve ‘’”

Is the site down?

I’m running Ubuntu on WSL:
Distributor ID: Ubuntu
Description: Ubuntu 22.04.1 LTS
Release: 22.04
Codename: jammy was the previous address of Parrot’s public server. The new one is, so you probably have an old PPA installed on your system, probably in /etc/apt/sources.list.d/sphinx.list that you can remove.

Thanks for your response. I’ve removed the entry from sphinx.list file & reran:
sudo apt update
sudo apt install parrot-sphinx

I’m still getting the following message:

Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
E: Unable to locate package parrot-sphinx

I’m a bit of a noob to handling package managers. Do I need the sphinx.list file at all now or can I remove the file? I see the latest instructions (Installation procedure - 2.15.1) don’t mention the sphinx.list file. Is there any additional commands I need to run related to GPG? Ex: I’m referring to the thread:
E: Unable to locate package parrot-sphinx on Ubuntu 18.04.5 LTS

Have you run the commands here: Installation procedure - 2.9.1 ?

After running them, you should have a file at this location:


What is its content?

I noticed that you are running ubuntu 22.04 while the current version of sphinx is not yet compatible with it. You need to wait for sphinx 2.10, and also for PC firmware releases compatible with ubuntu 22.04.

Besides, you are using WSL, which an environment that is not tested, therefore not sure to be working smoothly…

deb [signed-by=/usr/share/keyrings/] jammy main generic

Thanks for pointing that out. Looks like I’ll either need a dedicated machine or a local VM to run a version of Ubuntu compatible with Sphinx.
