Install TeXLive on Ubuntu

To install texlive2008

1. sudo mount -o loop textlive2008-20080822.iso /mnt

2. cd /mnt

3. ./install-tl -gui

If there is error about "Cannot load Tk, maybe something is missing" or "perl/Tk unusable, cannot create main windows.",

Follow its suggestion, visit  http://tug.org/texlive/distro.html#perltk

4. sudo apt-get install perl-tk

5. sudo ./install-tl -gui

Make wise choice, default dir /usr/local/texlive/, click Install TeX Live

Download TexMaker, Install it. In configure, add correct path for each executable file, 

such as /usr/local/texlive/2008/bin/i386-linux/latex. In this way, those programs can be found.

6. sudo vi ~/.bashrc  and/or sudo vi /root/.bashrc

Add one line at last

export PATH=$PATH:/usr/local/texlive/2008/bin/i386-linux

To launch the tlmgr, 

7. sudo su
8. tlmgr -gui

If the path is not set in the bashrc, there is error when you launch the tlmgr, even if you execute it from its directory. The error are like:

Can't exec "kpsewhich"

Can't locate TeXLive/TLPOBJ.pm in @INC

So just ass the path of TexLive installation directory.

It is better to install texlive to somewhere does not require root. i.e. /home/yourname/textlive . But the 7th step solves this problem.
