Description of my issue

Hi

I’m trying to install Photonix through Yunohost. It fails and gives me the following error:

ERROR - Unable to install photonix: An error occurred inside the app installation script

I don’t know what this means or how to fix it. In the log, there are also two warnings. I don’t know if they are causing the error:

WARNING - W: GPG error: http://cdn-fastly.deb.debian.org/debian buster-backports InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 648ACFD622F3D138 NO_PUBKEY 0E98404D386FA1D9
WARNING - E: The repository 'http://http.debian.net/debian buster-backports InRelease' is not signed.

Here is the full log:

Does anyone know how to go about fixing this? or working around it?

Thanks
\Martin

Hmokay that sounds like an issue that may have been triggered by something else before installing photonix …

Can you share the output of grep -nr 'debian.org' /etc/apt/sources.list* ?

Thank you for your reply. I tried installing it again and got the same problem and the output looks identical. Nonetheless, here is the new output: https://paste.yunohost.org/raw/puyuzigale

grep -nr 'debian.org' /etc/apt/sources.list*

Doesn’t output anything. The file /etc/apt/sources.list only contains

deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi

The file /etc/apt/sources.list.d/photonix.list contains

deb https://dl.yarnpkg.com/debian/ stable main

Does that help? I have other *.list files corresponding to other apps.

– Edit to add - -

The webadmin throws out an error when I try to update. And when I run sudo apt-get update on the command line I see that it’s the same public key error. So I update the distro, and then use checkrestart and clean up some old files. (I followed yunohost’s troubleshoot guide up until that point).

The public key error still persists, so I read up on keys and keyservers, and I try to add the keys in the error with

gpg --keyserver keyring.debian.org --recv-keys <PUBLIC_KEY>

Which gives me the following for both keys (except the first line, it only appeared when I ran the command for the first time)

gpg: keybox '/home/admin/.gnupg/pubring.kbx' created
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

And the error still persists. So based on this, it looks like the server can’t get the public keys for http://cdn-fastly.deb.debian.org/debian, or at least not from keyring.debian.org

Am I understanding the problem correctly or am I off on a wild goose chase?

– Edit again—

I tried getting the keys without specifying server:

$ gpg --recv-keys 648ACFD622F3D138
gpg: key DC30D7C23CBBABEE: new key but contains no user ID - skipped
gpg: Total number processed: 1
gpg:           w/o user IDs: 1

It still throws out the public key’s error.

Thanks for your help
