My Question or Issue

Hello, I've an error when updating software sources in Linux mint 22.1 :
W:GPG error: https://repository.spotify.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C85668DF69375001, E:The repository 'http://repository.spotify.com stable InRelease' is not signed., W:Updating from such a repository can't be done securely, and is therefore disabled by default., W:See apt-secure(8) manpage for repository creation and user configuration details., W:https://ppa.launchpadcontent.net/ernstp/mesarc/ubuntu/dists/jammy/InRelease: Signature by key 177961E789BE960FE5E59170B78C97EF9B2235DD uses weak algorithm (rsa1024), W:https://ppa.launchpadcontent.net/vincent-vandevyvre/vvv/ubuntu/dists/jammy/InRelease: Signature by key 7CAA00CD3DCA73E24812D646A5ADEEFF89F92A1A uses weak algorithm (rsa1024)

I tried to add the public key with command :

sudo curl -sS https://download.spotify.com/debian/pubkey_C85668DF69375001.gpg | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/spotify.gpg

But it didn't change anything, I always have this error.

It looks like your Spotify repository public key is missing or outdated. Since Ubuntu-based distributions (like Linux Mint) now use a different key management system, you’ll need to add the correct GPG key using a different method. Here’s how to fix it:

Remove the old Spotify GPG key (if it exists):

bash

sudo rm -f /etc/apt/trusted.gpg.d/spotify.gpg
Add the new public key the correct way:

bash

sudo mkdir -p /etc/apt/keyrings curl -sS https://download.spotify.com/debian/pubkey_0D811D58.gpg | sudo tee /etc/apt/keyrings/spotify.gpg > /dev/null
Update your repository entry to use the new key location:

bash

echo "deb [signed-by=/etc/apt/keyrings/spotify.gpg] http://repository.spotify.com stable non-free" | sudo tee /etc/apt/sources.list.d/spotify.list
Update the package list and install Spotify:

bash

sudo apt update && sudo apt install spotify-client

Let me know if you need more help! 😊

Hello,

thank you very much for your support.

I did all commands and checked the directories and files. But, when all was done "apt update" send me the same error :

W: Erreur de GPG : https://repository.spotify.com stable InRelease : Les signatures suivantes n'ont pas pu être vérifiées car la clé publique n'est pas disponible : NO_PUBKEY C85668DF69375001
E: Le dépôt http://repository.spotify.com stable InRelease n'est pas signé.

Sorry it's in french language, my system is n french.

It seems the signature cannot be checked because the system doesn't recognize the public key to check. And it said that the repository is not signed.

I don't understand.

I think I'll use a workaround by installing the flatpak from flathub. (system package is version 1.2.37, flatpak is in version 1.2.52). I must also remove the spotify repository from my software sources, if not i've always an error when updating the cache and it is a problem when upgrading Mint.

@Gebe_76

Hello again!

I did some research on your issue, and I just found out that Linux devices are not officially supported, and that might be the reason why you are getting these errors.

Cheers,

Thank you Ribezaz

Yes I think it is the problem. So the best is to use the flatpak in place of system repository, or simply use the web interface with any browser.

So still thanks for your help.
Friendly.

This always worked for me;

Just add the new rule (get it from install instructions) to your system, in this case it was;

curl -sS https://download.spotify.com/debian/pubkey_C85668DF69375001.gpg | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/spotify.gpg
echo "deb https://repository.spotify.com stable non-free" | sudo tee /etc/apt/sources.list.d/spotify.list

(just copy and then paste it (from the most recent install instructions) in your terminal)

and

sudo apt update && sudo apt upgrade -y

and your client will be updated..

There is an error at Step two.. before curl you need a pipe line break.

sudo mkdir -p /etc/apt/keyrings | curl -sS https://download.spotify.com/debian/pubkey_0D811D58.gpg | sudo tee /etc/apt/keyrings/spotify.gpg > /dev/null

@ribezaz Why are you clearly using AI to post answers in a community forum? This does not belong here.. Spotify on Linux is supported, but it's more of a side hustle for the devs.

Not only his answer makes no sense whatsoever, it also got accepted by the OP. For god, the issue comes directly from the fact the key gets installed when you get the official Linux package lol

Nonetheless, the best solution is to go back to the "Download Spotify for Linux" (https://www.spotify.com/download/linux/) page and grab the key from there again. This way, you're sure to get the most updated key, instead of one frozen as a post from someone else above.
