sudo apt-get -y -u dselect-upgrade --force-yes causing to remove VIM

When I am running command

Code:

sudo apt-get -y -u dselect-upgrade --force-yes.

It is causing VIM to get remove.

I need to understand WHY ?

Before

Code:

sudo apt-get -y -u dselect-upgrade --force-yes.

I am running

Code:

sudo dpkg --set-selections < packages-64.txt'

and in this pakage-64.txt package selection state for VIM is install but it uninstall it.

Also, when I execute sudo apt-get -y -u dselect-upgrade --force-yes it :-

Reading state information...
The following packages will be REMOVED:
acpid* apparmor apport* apport-symptoms* apt-xapian-index byobu cloud-init
cloud-initramfs-growroot cloud-utils command-not-found*
command-not-found

The pakage marked with * are listed to purged in pakage64.txt however the pakage which are not with * are not listed to purged VIM is also appearing without *

so look like the command:-

Code:

sudo apt-get -y -u dselect-upgrade --force-yes

select some packages to remove I need to understand on what grounds and if I dont want any package to get remove how can I control?

Hi,

I strongly recommend not to use --force-yes. From the apt-get man page:

Code:

      --force-yes

          Force yes; this is a dangerous option that will cause apt to continue without

          prompting if it is doing something potentially harmful. It should not be used

          except in very special situations. Using force-yes can potentially destroy your

          system! Configuration Item: APT::Get::force-yes.

Have you tried without this option?

Also, did you do a standard "apt-get update && apt-get upgrade" first?

And finally, what distro are you running and what version?

Evo2.

1.) I understand that force is not recommended use however I am just building machine as per the list defined in packages-64.txt
NO, I have not tired with this option because I have created the script for it and wanted it to run unattended.

2.) Yes I did update and upgrade as:-

sudo apt-get -V update
sudo apt-get -V -y dist-upgrade --force-yes

3.) Distributor ID: Ubuntu
Description: Ubuntu 12.04.4 LTS
Release: 12.04
Codename: precise
