Running any sudo apt-get command gives the error:

/usr/bin/apt-get: 1: /usr/bin/apt-get: Syntax error: end of file unexpected

(see Related question)

Is there a way to reinstall the apt-get program or replace the file /usr/bin/apt-get ?

Admittedly that is a duplicate but considering it did not receive a working solution I am inclined to leave this question open. – Mokubai Sep 13 '13 at 16:59

Disclaimer: The output shown is taken from a debian system, as I don't have access to a ubuntu machine. Ubuntu should be sufficient similar.

apt-get is an Advanced front-end for dpkg (according to its description), so you should still be able to you dpkg. First, determine your apt version:

$ dpkg -l | grep apt | head -n 1
ii  apt                                                      Advanced front-end for dpkg

Grab the appropriate deb package from [][1] (I took the link from the linked question -- I'm absolutely not sure, if this is the right repository for your ubuntu version!).

Then you can try to remove apt from your system

$ dpkg -r apt

and reinstall it:

$ dpkg -i apt_[...].deb

dpkg -r does not touch the conffiles, so if that does not work, you can try to use dpkg -P apt, which does a purge and removes also the conffiles (from man dpkg: Conffiles are configuration files that are listed in the DEBIAN/conffiles control file)

Thanks. I get dpkg: dependency problems prevent removal of apt: ubuntu-minimal depends on apt. unattended-upgrades depends on apt. ubuntu-extras-keyring depends on apt. – user224461 Sep 15 '13 at 18:31
@user224461: You can force the removal with dpkg --force-all -r apt. But please double-check that you have the correct deb package of apt at hand! – mpy Sep 15 '13 at 18:36
Ok thanks. How do I know which of the apt packages I need? (32-bit ubuntu 13.04) I have apt apt_0.9.7.7ubuntu5_i386.deb? apt_0.9.7.7ubuntu4_i386.deb? or apt_0.9.7.5ubuntu5_i386.deb? apt_0.9.7.5ubuntu5.5_i386.deb.. – user224461 Sep 16 '13 at 9:03
Since you have apt it is one of the apt_0.9.7.7 packages. But I don't know what's the difference between the ubuntu4 and ubuntu5 suffix, as I don't use Ubuntu myself, sorry. – mpy Sep 16 '13 at 9:27
Many thanks, it worked by "sudo dpkg --force-all -r apt" then i tried "dpkg -i apt_[...].deb" with the ubuntu5 version of the .deb file but got an error removed again and reran with the ubuntu4 – user224461 Sep 16 '13 at 20:04
