I have been trying to install Acrobat Reader on my Ubuntu 12.04.1. In the be;ggining, I tried to install it from the software-center, but it crashes with the report:

(Reading database ... 189311 files and directories currently installed.)
Unpacking acroread (from .../acroread_9.5.1-1precise1_i386.deb) ...
dpkg: error processing /var/cache/apt/archives/acroread_9.5.1-1precise1_i386.deb (--unpack):

As as solution, I tried to install it via terminal, with the

$sudo apt-get install acroread

and receive the following:

I've already tried to upgrade and update the apt-get, also tried to remove and re-install the software-center, tried deleting the "problematic" files and re-updating the apt-get... Nothing seems to work... Any solutions?

This isn't an answer to your question, but it is recommended to not install adobes reader since it is bloated and a security risk. If you use Chrome it comes with its own built in PDF reader and Evince is good for the desktop and comes default. Any reason you need the Adobe version? – Goddard Sep 17 '12 at 18:21
Looks like you have a conflict with the package adobereader-ptb. Try to remove it by sudo apt-get remove adobereader-ptb and try to install acroread again. The remove will show you if it removes packages that depend on adobereader-ptb. This way you can see why it was installed. Make sure it doesn't remove anything you still need. – André Stannek Sep 17 '12 at 18:42
@Goddard I try to avoid the Acrobat Reader if possible, but sometimes I have documents that only work with Acrobat (Mostly forms with text fields to fill in). +1 anyway :-) – André Stannek Sep 17 '12 at 18:45
Have you tried the Google Docs extension for your browser? – Goddard Sep 17 '12 at 19:06
Nope, will try it next time. Thanks! – André Stannek Sep 17 '12 at 19:10

open your terminal and type this one by one

sudo dpkg -r acroread_9.5.1-1precise1_i386.deb
sudo apt-get -f install
sudo apt-get update
sudo apt-get upgrade
