Hello, very sorry for the ultra-generic uestion, but it's impossible for me to find a solution googling it... I'm using Enigmail 1.9.6.1 on Thunderbird 45.8.0 on Xubuntu 16.04 and I normally sign my message but I always get a 'key can't be used for encryption' message when I try to send an encrypted mail. In GPA too also I read 'The key has both a private and a public part. The key can be used for signing but not for encryption'. My key ID is: 9ADB5592 Any suggestion about what I should check to...
