Debian apt-get reports GPG error

[KernelPanic]

Dear Sirs and Madams!

I've installed PicoScope software on Debian Linux and it works fine. However, when I update the system using

Code: Select all

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade && sudo apt-get autoremove

I get following GPG error:

Get:9 https://labs.picotech.com/debian picoscope InRelease [3,654 B]
Ign:9 https://labs.picotech.com/debian picoscope InRelease
Fetched 187 kB in 0s (249 kB/s)
Reading package lists... Done
W: GPG error: https://labs.picotech.com/debian picoscope InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6964D13AA2A43CCE
W: The repository 'https://labs.picotech.com/debian picoscope InRelease' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

How do I retreive your public key (from Picotech) so this warning/error will dissapear?

Sincerely,
M.

Code: Select all

wget -O - https://labs.picotech.com/debian/dists/picoscope/Release.gpg.key | sudo apt-key add -
