How to install apt package in debian?

Question

I am having Debian GNU/Linux 6.0.4 (squeeze). By mistake all the apt files are removed from my OS. I am trying to install package "apt_0.9.7.1_amd64.deb". But while installing the package i am getting the following errors :

Unpacking replacement apt ...
dpkg: dependency problems prevent configuration of apt:
 apt depends on libapt-pkg4.12 (>= 0.9.7.1); however:
  Package libapt-pkg4.12 is not installed.
 apt depends on libstdc++6 (>= 4.6); however:
  Version of libstdc++6 on system is 4.4.5-8.
 apt depends on debian-archive-keyring; however:
  Package debian-archive-keyring is not installed.
dpkg: error processing apt (--install):
 dependency problems - leaving unconfigured
Processing triggers for man-db ...
Errors were encountered while processing:
 apt

Can anyone know how to install the apt package? or are there any other ways to install the package.

While using any command like sudo apt-get update etc. I am getting error

apt : Depends: debian-archive-keyring but it is not going to be installed

For installing debian-archive-keyring I need apt and for apt I need debian-archive-keyring. Please suggest any solution.

Answer 1

Since apt is no longer present on your system you'll have to fix this manually.

For me this worked on Ubuntu 13.10:

Downloaded apt_1.0.1ubuntu2.5_amd64.deb : http://packages.ubuntu.com/trusty/apt

Try to install it using dpkg :

sudo dpkg -i apt_1.0.1ubuntu2.5_amd64.deb

You might get error like:

Unpacking apt (from apt_1.0.1ubuntu2.5_amd64.deb) ...
dpkg: dependency problems prevent configuration of apt:
 apt depends on libapt-pkg4.12 (>= 0.9.16); however:
  Version of libapt-pkg4.12:amd64 on system is 0.9.9.1~ubuntu3.

To fix this download correct version of the dependency from the same site .

And install that:

sudo dpkg -i libapt-pkg4.12_1.0.1ubuntu2.5_amd64.deb

Now you should be able to repeat the first command and install apt .

Note: The package versions may be different depending upon your version of Ubuntu. To locate the correct version use the menu in the header to select your ubuntu version:

尝试su在 tty 环境（无 gui）中 root，然后尝试apt-get update和/或apt-get -f install

尝试使用 aptitude 或下载该特定包（如有必要，带有依赖项）并使用 dpkg -i your-downloaded-packages*.deb 安装它

Try this one-liner, it has helped me most of the time, when I get dependency issues.

Enter the following command sudo dpkg install -f . I hope this helps.
