Hello !

For several days now, I get the following error when updating or 
upgrading my TDE.� Note: I am using the development archive for 
debian/buster or debian/stretch testing; i.e., deb 
http://mirror.ppa.trinitydesktop.org/trinity-sb buster deps-r14 main-r14 
(or buster if testing buster).

The error messages from stretch update:

W: GPG error: http://mirror.ppa.trinitydesktop.org/trinity-sb stretch 
InRelease: The following signatures couldn't be verified because the 
public key is not available: NO_PUBKEY C93AF1698685AD8B
W: The repository 'http://mirror.ppa.trinitydesktop.org/trinity-sb 
stretch InRelease' is not signed.
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.

A similar error message if updating the buster archive.

Yes, I have installed

ii� trinity-keyring� 4:14.0.7~pre3-0debian9.0.0+2 all� GnuPG key of the 
Trinity Desktop Environment repository

and, I have also tried the command

wget http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-keyring.deb

but cannot seem to rid the error.

The testing is going fine and I can actually install the packages with 
the "--allow-unauthenticated", but of course, I would rather not !

Anyone else with this problem?� Is there a way to correct it on my end?
