Trying to run any apt-get commands from the terminal gives me a syntax error. Synaptic and Software Center work fine (Ubuntu 13.04).

For example:

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

I was installing icedtea-7 java browser plugin for online banking around the time the error started but not sure if related. Any ideas?

Thanks

Updated: All other sudo commands seem fine.

Could you post your /etc/apt/sources.list file? Can you run other sudo commands OK? –  terdon May 15 '13 at 10:54
    
Other sudo commands run ok. I posted sources.list, thanks –  user224461 May 17 '13 at 15:19
    
Well, your sources seem OK. Could you also post the output of these commands: which apt-get, file $(which apt-get) and ls -l $(which apt-get)? –  terdon May 17 '13 at 15:42

A good start for fixing apt problems is usually cleaning the cache and updating the indices: $ sudo apt-get clean $ sudo apt-get update

If the problem persists, some of the list files might be corrupted. Removing them manually and then updating the indices works around that problem.

Any "sudo apt-get" command gives the same error –  rigyt May 15 '13 at 9:04
    
Has the apt-get command maybe been overwritten? What does "$ which apt-get" show? Should be /usr/bin/apt-get. What is the output of "$ ls -lh /usr/bin/apt-get" ? The size should be around 187k. –  TeTeT May 15 '13 at 19:46
    
"which apt-get" does show /usr/bin/apt-get and the file is 190.9kB –  user224461 Sep 13 '13 at 9:43
