On their Installation procedure page, when I do a
sudo apt-get update from the /etc/apt/sources.d/sphinx.list file I get the error “Err:4 http://plf.parrot.com/sphinx/binary buster/ InRelease
403 Forbidden [IP: 220.127.116.11 80]
Reading package lists… Done
E: Failed to fetch http://plf.parrot.com/sphinx/binary/buster/InRelease 403 Forbidden [IP: 18.104.22.168 80]
E: The repository ‘[same address as above, due to new user restrictions]’ is not signed.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.”
After reading the manual on “apt-secure”, I tried changing the sphinx file
deb [the address generated by the code from the installation page] adding
deb [ allow-insecure=yes trusted=yes allow-downgrade-to-insecure=yes ] …
I have also succesfully installed everything by following their installation page.
I am using Debian 10 (buster) with kernel “Linux debian 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2 (2019-08-28) x86_64 GNU/Linux”.
