Another day, another challange 🙂
after using aptitude update in console I got “WARNING: The following packages cannot be authenticated!”. NO_PUBKEY E9C74FEEA2098A6E
So – the solution is:
gpg –keyserver keys.gnupg.net –recv-key E9C74FEEA2098A6E
gpg -a –export E9C74FEEA2098A6E | sudo apt-key add –
And another tip – you must have open port 11371to get key from keys.gnupg.net.
Have fun 🙂
