I recently installed Kali Linux in my system. It came with a preinstalled Iceweasel. However, instead of Iceweasel I wanted to install firefox so I followed this guide and installed firefox successfully.
Now whenever I invoke
apt-get it shows many pre-installed packages as "automatically installed and no longer required":
abhishek@ab-linux:~$ sudo apt-get install [sudo] password for abhishek: Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: empathy empathy-common fonts-cantarell gcalctool gnome-backgrounds gnome-dictionary gnome-font-viewer gnome-icon-theme-extras gucharmap libavahi-gobject0 libcaribou-gtk-module libcaribou-gtk3-module libchamplain-0.12-0 libchamplain-gtk-0.12-0 libgdict-1.0-6 libgdict-common libgeocode-glib0 libtelepathy-farstream2 nautilus-sendto-empathy sound-theme-freedesktop telepathy-gabble telepathy-logger telepathy-salut vino Use 'apt-get autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 35 not upgraded. abhishek@ab-linux:~$
abhishek@ab-linux:~$ uname -a Linux ab-linux 3.7-trunk-amd64 #1 SMP Debian 3.7.2-0+kali8 x86_64 GNU/Linux
How to mark these package as important and required?
