You can do a couple of things for avoiding this. Setting the DEBIAN_FRONTEND variable to noninteractive and using -y flag. For example:

export DEBIAN_FRONTEND=noninteractive
apt-get -y install [packagename]


If you need to install it via sudo, use:

sudo DEBIAN_FRONTEND=noninteractive apt-get -y install [packagename]参考资料：
