Super+u [System Update] vs Synaptic>>Mark all possible upgrades

hi all again,
as i said in a previous post, i'm switching from ubuntu+gnome and trying to get familiar with crunchbang+openbox+terminal

as to updating the system software,

1) what's the difference between *update* and *upgrade* ?
2) is CUI *super+u (system update via terminator)* equivalent to GUI *marking all possible upgrades in synaptic* ?

i'm asking this because in terminator some packages are marked as *having been kept back* and wouldn't be installed
whereas in synaptic there's no mention of kept-back packages and they would all be installed -- why is that?

thanks for any explanation

Hello gnema

You can run the equivalent of "Mark all possible upgrades" with the system-update script by using an addition argument:

system-update -f

Or

system-update --full

Using the system update script without the additional command is somewhat safer as updates to the Kernel etc. will not be downloaded and installed. The script is just a wrapper for the standard apt-get commands, which are:

Refresh your sources:

sudo apt-get update

Upgrade available packages:

sudo apt-get upgrade

Upgrade available packages, including Kernel updates etc:

sudo apt-get dist-upgrade

Hope this helps.

Why does the update script not download and install new Kernels?

if i got it right, the system-update script with *no additional argument*
will issue a sudo apt-get upgrade

in order to have a sudo apt-get dist-upgrade the script must be run with *-f* or *--full*
thus handling new packages that imply a change [removals and/or new dependencies]
of the current install satus

i've found some interesting info in
