I have Android and Gemian TP3 on my Gemini.
If I do sudo apt-get update, I get an error message, not always exactly the same but this one is typical.
W: GPG error: http://gemian.thinkglobally.org/stretch stretch InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6669378035F4918C
W: The repository 'http://gemian.thinkglobally.org/stretch stretch InRelease' is not signed.
I don't fully understand the implications of this. Can I force the upgrade to work with an unsigned repository somehow, and if so is it wise to do so?
Is anyone else getting this? Or am I special?
Thanks
Neil
