Shellfox failed to run command

It seems that Shellfox is not fully installed!

Shellfox, unlike most extensions, requires a script to be installed on your computer. This script, shellfox.sh, is what allows us to execute shell commands.

Completing installation

To install Shellfox’es local component:

  1. Download the script through the repository’s ZIP archive here.
  2. Extract the ZIP archive: This leaves a shellfox/ folder.
  3. Open a terminal within that shellfox/ folder.
  4. Run the command, $ sudo make native-install
  5. You’re done: Party!!

From a terminal, that would look something like:

$ curl https://hak.xwx.moe/jadedctrl/shellfox/archive/master.tar.gz | tar -xzv
$ cd shellfox/
$ sudo make native-install
