[tex-live] Where is the root dir of my Tex Live installation

[Gerald Pechoc]

Hi,


I have now deinstalled all tex-components I could find.
The basic installation using the package manager.

After the computer was "clean" I installed TEX Live from the dvd (iso file).
After that I changed the path in .bashrc .

Then I installed Texmaker, first from Ubuntu Package Manager, but that 
failed at the end. After deinstallation I tryed the installation from 
downloaded .deb package 
(http://www.xm1math.net/texmaker/download.html#linux).

These errors appeared also after restart and new installation:

(Reading database ... 95% (Reading database ... 100% (Reading database 
... 374801 files and directories currently installed.)
Unpacking texmaker (from .../texmaker_ubuntu_12.04_4.1_amd64.deb) ...

Does anyone know what I have to do?
Any help is welcome...
