Run Internet Explorer on Ubuntu Linux

You have to enable universe packages first. It is also recommended that you use the official winehq ubuntu package:

1) Open a terminal

2) Open /etc/apt/sources.list

$sudo gedit /etc/apt/sources.list

3) Uncomment (or add) following lines:

deb http://us.archive.ubuntu.com/ubuntu edgy universe

4) Add this line:

deb http://wine.budgetdedicated.com/apt edgy main

5) Close gedit. Update and install wine and cabextract:

$wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- sudo apt-key add -

$sudo apt-get update

$sudo apt-get install wine cabextract

6) Download IEs 4 Linux and install

$wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz

$tar zxvf ies4linux-latest.tar.gz

$cd ies4linux-*./ies4linux

Note for Dapper users:

if you use ubuntu dapper, replace edgy with dapper on lines above. Note for Feisty users (7.04): if you use ubuntu Feisty, replace edgy with feisty in the lines above. Also replace gedit with kedit

if running Kubuntu instead of Ubuntu.
