When I add the the OMV Extras plugins repository, I usually use the commands:
gpg --recv-keys EDEE7D73 && gpg --export EDEE7D73 | sudo apt-key add -
or
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv EDEE7D73
However, whgen I run the command "sudo apt-get update", I'm getting the following error message:
[...]
Fetched 4,327 B in 11s (362 B/s)
Reading package lists... Done
W: GPG error: http://packages.omv-extras.org erasmus InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AAA3036B30B2308A
How can I rectify this situation to move forward?
