E:Unable to locate package libssl-dev:i386

装下面3个包的时候发现出现下面错误，更换源也没用

sudo apt-get install -y libssl-dev libssl-dev:i386
sudo apt-get install -y libncurses5-dev libncurses5-dev:i386
sudo apt-get install -y libreadline-dev libreadline-dev:i386

后来查到是说没有启用i386架构

dpkg --add-architecture i386
apt-get update

再装就能装上了，原帖地址
