方法1

报错显示是这个key非法，所以添加key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EC34ED227AFAE3F2

可能又报错，也可能成功

Executing: /tmp/apt-key-gpghome.kqQzk2dNQt/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys EC34ED227AFAE3F2
gpg: keyserver receive failed: No data

方法2

把刚才报错的那个网址前面的勾取消，再进行apt-get udate就可以了。

注：如果产生别的报错，可以再尝试去切换源试试
