LL system update script is using apt-get:

/usr/scripts/updates

Code:
sudo apt-get update && sudo apt-get upgrade

As I was trying out Debian Jessie lately I noticed that aptitude seems to be considered a better choice to do system updates than apt-get because it offers smarter handling of dependencies and has some other benefits. The equivalent command would be:

Code:
sudo aptitude update && sudo aptitude safe-upgrade

I have done a test run of both commands (actual updates were aborted) and the output is quite different:

apt-get:

aptitude:

I'm wondering what experts think about all this.

apt-get and aptitude have different rules.

Code:
man aptitude

Code:
man apt-get

aptitude safe-upgrade upgrades currently installed packages and can install new packages to resolve new dependencies, but never removes packages unless they are unused.
apt-get upgrade upgrades currently installed packages, but never installs or removes packages.
So

Code:
apt-get upgrade

is comparable to

Code:
aptitude --no-new-installs safe-upgrade

Sometimes aptitude has better rules, sometimes apt. Linux Lite prefers apt-get.

Hmmmm

Just checking a few things. I did not know aptitude was also installed along side apt-get in Linux-Lite on a default
2.4 install. Not that I am sooooo bored that I would screw with dist-upgrade scripts or package management
myself in this distro.

I have other test boxes for breaking installs for that.
