I've plain Ubuntu 14.04 Server (64-bit) installation.

When use:

```
sudo apt-get update

```

Print this error:

```
....
Hit http://security.ubuntu.com trusty-security/universe Translation-en
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 

```

After removing tmp.i `/var/lib/dpkg/updates# sudo rm tmp.i` apt-get update went OK but...

When I tried 'sudo apt-get upgrade':

```

I can't find any solution for that so far on web, tried many ways but nothing worked...
