There are a variety of ways to install LO for Debian OS's. Some are
harder than others, and some are easier.
What no one has mentioned is the use of script files. They will do much
of the work for you. Planning how to install the Deb files is important.
If you have LO from your OS, you need to use Synaptic (Step#1 mentioned
above.) But this is the only time you need to do this. dpkg (installs
the Deb files) writes the new files over the existing files. There is no
need to remove them.
Extract the installation folder and always place it in the same
location. (This is important for the contents of the script file.)
Example of the script file:
#!/bin/sh
cd
/home/dan/Downloads/LO/LibO_3.6.5.2_Linux_x86-64_install-deb_en-US/DEBS/
sudo dpkg -i *.deb
cd desktop-integration
sudo dpkg -i *.deb
This looks like a lot of typing, but it is not really. Besides much of
it is used over and over again. The third line is the longest. "cd
/home/dan/Downloads/LO/" is the location for the installation folder
that you extracted. "LibO_3.6.5.2_Linux_x86-64_install-deb_en-US" is the
name of that folder.
I do not like to type long names like the name of the installation
folder, so I look for a short cut. I use the file browser (Nautilus) to
go to this folder's location, I can right click on the folder and select
Properties. There at the top is the folder's name highlighted. Ctrl+C
copies the name, and I paste it into the third line. I also erase the
name of the previous folder. Another method: erase the number of the
previous LO version and type in the new number. In this case, replace
3.6.5.2 with 4.0.0.3.
What this does: installs the Deb files and desktop integration items.
The script file needs to be executable when it was first created. To do
this right click the script file, select Properties -> Permissions.
Click the box labelled "Allow executing the file as a program."
The location of the script file might be important also.
So actual steps to install 4.0.0.3:
1) Download the file to /home/dan/Downloads/LO/.
2) Extract the downloaded file to the same location.
3) Update the third line of the script file using either method using
gedit.
4) In the file browser, double click the script file.
5) Click the button "Run in Terminal".
6) Type your password.
7) Close the terminal.
The first two steps involve only clicks. Step 3 can involve only using
the mouse, or typing 4 digits and 3 periods. Only step 6 involves typing
with the rest done by mouse clicks.
