A Synaptic search yields 22 items. Nothing jumps out as being a

Software Center.

There is no "master". However, if you installed it using a single
package that then pulled all of the other packages, you can easily
remove it with a command line thus:
$ sudo aptitude --purge purge main-package-that-pulled-the-others
This will purge the main package (e.g., the one that you used to pull
all of the other ones) and it will purge any other associated packages
that are *automatically* installed *and* have no other dependencies.

This is another post I'm saving for later reference. That's good
info. LibreOffice wasn't originally in the Ubuntu Repositories, so I
didn't use synaptic. Again, I don't wish to get rid of it, so this is
all hypothetical.<br>
<br>
For PC #1, I used this command, per the LibreOffice website, executed
from within each of three DEBS directories extracted from tarballs.<br>
<br>
<code>sudo dpkg -i *.deb<br>
<br>
</code>I'm afraid I don't know what the procedure did, other than that
it installed LibreOffice and it appears to work. Later, I learned
about the PPA. I'm working on activating that on PC #1 so I can get
the auto updates going. <br>
<br>
On PC #2, I used the following commands to install LibreOffice from the
PPA. I didn't use synaptic this time either.<br>
<br>
sudo add-apt-repository ppa:libreoffice/ppa<br>
sudo apt-get update<br>
sudo apt-get install libreoffice<br>
sudo apt-get install libreoffice-gnome<br>
<br>
Again, this did LOTS of stuff, I know not what. I wouldn't know what
synaptic record to purge if I wanted to.<br>

<pre wrap="">I'm not sure that there is a way to directly translate that into a GUI
with a reasonable number of steps. The packaging systems on (most)
distributions are quite a bit more flexible than the packaging scheme
that Microsoft uses (that is, the Windows Installer package management
system, also known by some as the MSI package management system).

I don't have to use the GUI. I just prefer to most of the time.
However, I do realize there are times you just need the command line.
I think my sister is vaguely aware of the command line, and my Dad and
son are not hardly aware of it at all.<br>
<br>
Here's something I've found the command line useful for on both Windows
and Linux. That is getting directory listings with odd
characteristics. For example:<br>
<br>
Windows: dir c:\mydir /s /os > dir.txt - This will take a directory
listing of c:\mydir, and all subdirectories, and order the list by file
size, and send the result to dir.txt. Now you wouldn't want to do this
against c:\ (the root directory) unless you want to wait an hour and
get a text file with 2+ million lines in it. One neat thing you can do
with the resulting text file is print it, which you can never do from
any graphical file browser I've seen.<br>
<br>
I'm sure you can do something similar with the ls command in Linux. I
just haven't taken the time to figure it out.<br>
<br>
I also sometimes use the command line for copying files, particularly
if I want to use wildcards, and I sometimes use the command line for
checking the IP address of a machine and the status of it's network
interfaces.<br>
<br>
Sincerely,<br>
