Couldn't add sparky repository to Debian testing

[Chdslv]

Tried to add sparky repo to debian testing distro, other than Sparky Linux. I got this after update

The repository 'https://sparkylinux.org/repo testing Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure (8) manpage for repository creation and user configuration details.
E: Failed to fetch https://sparkylinux.org/repo/dists/testing/main/source/Sources  gnutls_handshake() failed: Public key signature verification has failed.
E: Some index files failed to download. They have been ignored, or old ones used instead.

Sparky keyring added through wget, though.

Public key signature verification has failed.

Did you follow the wiki instruction? If yes, there is sudo in use, but pure Debian doesn't use sudo, so try:

Code Select Expand

su
wget -O - https://sparkylinux.org/repo/sparkylinux.gpg.key | apt-key add -
apt-get update

Yes. Exactly as in the wiki.

So did you use sudo, but do you have sudo configured?
If not, use as I post here.

Yes, I have sudo configured and its done with sudo. apt-get update won't work without sudo. Like I wrote in the OP, I had sparky keyring added. Everything was done as in the wiki on Sparky Repository.
