gnupg,gnupg2 and gnupg1 do not seem to be installed,but one of them is required for this operation

在安装cuda时报错‘gnupg, gnupg2 and gnupg1 do not seem to be installed,but one of them is required for this operation’

尝试了

sudo apt-get update && apt-get install -y gnupg2

没用，会报其他错误

直接

sudo apt-get install gnupg

成功。

一步一坑…
