What is wrong with apt-get?

Question

I can see and apt-get in /usr/bin/:

gradinafrica@host:/usr/bin$ ls -l apt-get
-rwxr-xr-x 1 root root 178608 Apr 20  2012 apt-get

But when I try to run it, I get

gradinafrica@host:/usr/bin$ apt-get
-bash: /usr/bin/apt-get: No such file or directory

I think I may have messed it up. Is there a way to reinstall it without completely reinstalling Ubuntu?

I'm on Ubuntu 14.04 LTS, btw

EDIT:

PATH: /home/gradinafrica/.dnx/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Also, sudoing and/or running directly from /usr/bin (ie cd /usr/bin && sudo ./apt-get) give the same output; they don't help.

That is a really old version of apt. I think the last security update for apt was on october of 2014 and should at least have a different build id.

In any case, run the following commands:

cd
wget http://security.ubuntu.com/ubuntu/pool/main/a/apt/apt_1.0.1ubuntu2.5_amd64.deb
sudo rm /usr/bin/apt-get
sudo dpkg -i apt_1.0.1ubuntu2.5_i386.deb

please post any errors

Okay, since it didn't want to install at first, we can at least copy the new apt-get files to where they need to go to get things started. Run the following commands:

cd 
mkdir aptget
cp apt_1.0.1ubuntu2.5_i386.deb aptget
cd aptget
ar xvf *
tar xvf data*
sudo mv ./usr/bin/apt-get /usr/bin
sudo mv ./usr/bin/apt /usr/bin

Now, run apt-get:

sudo apt-get update
sudo apt-get clean
sudo apt-get -f install

You're currently in /usr/bin, therefore

If you want to run an executable file in the directory you're currently browsing, you should go for

$ ./executable_name

and not

$ executable_name
