Signed builds

Since 2011-05-17

To verify their signature, our GPG public key has to be added into apt keyring.

Run the following commands:

sudo apt-key adv –keyserver keys.gnupg.net –recv-key 0x810273C4

Then, update your lists of available software packages

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install sogo

From that point, apt-get should not complain about package signatures anymore.

 

That’s!!
