How to get apt after I accidentally uninstalled it [duplicate]

  • 772

Is it possible to use dpkg to install apt? It was uninstalled accidentally. If not, how can I get apt without reinstalling Ubuntu?

Edit: The following is what I get when I try to install apt with dpkg...

root@ben-HP-ENVY-dv4-Notebook-PC:/home/ben/Downloads# sudo dpkg -i apt.deb(Reading

  1. Yes I did it. I got into the same problem when I tried to install oracle-java7-installer with 

    sudo apt-get -y install oracle-java7-installer

    It told me that I'm going to do a very harmful thing (Remember I'm running trusty unstable development release) but I said 'Yes do as I sak' and it started removing everything including itself 'apt' so I forced stopped it. Coming back to the question, just download apt from

    http://packages.ubuntu.com/trusty/amd64/apt/download

    replace trusty with your release name and then run

    sudo dpkg --install apt_0.9.15.4ubuntu4_amd64.deb

    and that's it. It worked for at least.

  2. You can try to find a deb package for it, and use dpkg -i <package> or for aptitude.

    Try to install the source code, as it was already installed, should resolve dependencies and inside de folder run:

    ./configure 
make
sudo make install
