Problem downloading ArduPilot

I’ve ran the following command:
pi@navio: ~ $ sudo apt-get update && sudo apt-get install apm-navio2

And ended up with the following error:

Could somebody help? I’m new to the raspberry and navio.

Same result/error as well.

@george.staroselskiy, @mikhail.avkhimenia, any insights/solutions?

GPG key had a wrong expiration date, will be fixed ASAP. Sorry for the inconvenience.

Guys, sorry for the inconvenience.

I updated the docs on apm-navio2 package installation.

You’ll need to add a new GPG key by issuing this command:

wget -qO - | sudo apt-key add -

After that everything should work as usual.

Excellent, working now and moving forward.


I’m considering this issue resolved and hence closing the thread. Thank you, guys!
