Different output of apt-get and aptitude for package upgarde


Hi
Normally I use apt-get for to upgrade my Debian system. Today i tried to compare apt-get and aptitude with respect to system upgrade. Surprisingly I got different results.

Code:
sudo apt-get upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
  openjdk-7-jre openjdk-7-jre-headless
The following packages will be upgraded:
  libtiff5
1 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
Need to get 213 kB of archives.
After this operation, 44.0 kB disk space will be freed.
Code:
sudo aptitude safe-upgrade
Resolving dependencies...                
The following NEW packages will be installed:
  libsctp1{a} lksctp-tools{a} 
The following packages will be upgraded:
  libtiff5 openjdk-7-jre openjdk-7-jre-headless 
3 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 45.9 MB/45.9 MB of archives. After unpacking 9,130 kB will be used.
What is behind these results? Which method is safer?

Use 'aptitude full-upgrade' to ensure your system is up to date.

The results above beg the question of what you have done to cause apt-get to be holding back those packages.

"apt-get upgrade" will not use non-installed packages if you don't ask it to do so (shouldn't happen in stable though, use dist- or full-upgrade as "descendant_command" already mentionned).

Both.
At the end, your package manager is still DPKG.
As long as it can keep track of everything, their's nothing to worry about.

PS: ... one other user tool is the new "apt" binary (as in: "apt install foobar), it aims to combine most lower level tools with some extras (like a nice progress bar).
