# it is like do the whole system upgrade

apt-get dist-upgrade

# search the database with the keyword

apt-cache search keyword

# show the keyword status, like version, description

apt-cache show keyword

# install the keyword

apt-get install keyword

# list the related file system path with the keyword.

dpkg -L keyword
