Finding the search for info on the internet somewhat frustrating.
Too much information, for my quick-fix aims.
Losing track of what I'm doing. Seriously.
Reading some forum, blog or article or other, I'll run a command, install or remove a program ... and then find myself wondering what it was that I did, whether it was enough and so on.
FLASH
Take Adobe Flash Player: I removed with a sudo command, but haven't checked to make sure it is indeed gone.
Somewhat confused about dependencies. Not sure if they're separate programs that rely on a given program, or whether dependencies are off-shoots of primary/key programs. But I am rather lazy and haven't really done much in the way of reading.
Anyway, I'm sort of stuck wondering if Flash is gone and how to verify that.
Then there's the question of installing/enabling alternatives to Flash.
Do you or don't you? Browser appears to have what I assume are inbuilt alternatives. But there's also the alternatives mentioned in an earlier post, that might be worthwhile considering.
JAVA
Seeing Java's full of holes, I figure it's not worth having.
So I go ahead and remove - or I think I remove. But I'm not sure it's gone.
When I run: java -version command, terminal throws up:
the program 'java' can be found in the following packages:
* default-jre
* gcj-4.8-jre-headless
* openjdk-7-jre-headless
* gcj-4.6-jre-headless
* openjdk-6-jre-headless
Try: sudo apt-get install <selected package>
So I'm going to guess that Java's not gone & I have to figure how to remove, entirely.
JUNK DOWNLOADS
Fiddling around, I downloaded some crap I somehow don't think I really want. Can't even remember what it was now. Some Red Hat thing, I think it was. So that's another mess I have to sort out - maybe. Otherwise, I can just ignore it, and tackle removal when I know what I'm doing ... and find out what it was (ummm, because I didn't take notes & can't remember / although I think there's a command to list programs somewhere):
RUN RESULTsudo dpkg -list
Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;
Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !
GENERAL COMMANDS
Then I thought I'd check out the Zorin forum, generally before moving onto specifics:
Any 3rd party packages that you might want to install should end with ".deb" or "all.deb" and should downloaded from a known and verified source/location
[ie download from safe download site]
Select correct package for 32-bit or 64-bit.
http://pkgs.org/
For installing single packages, install the app "Gdebi"
sudo apt-get install gdebi
The link meant nothing to me. Don't know what I'm looking at at the link.
But I think, hey, I can do with a single-package install thingy. So I load gdebi.
Back to the forum:
Do not try and use "rpm" packages if you possibly can as they are designed for another type of packaging system (Redhat Package Manager)
To convert RPM packages to DEB packages, use "Alien":
https://help.ubuntu.com/community/RPM/AlienHowto
Hmmm ... don't think I'll be tackling Alien any time soon.
But this did grab my attention & Synaptic looks like a good plan:
sudo apt-get remove [specify program]
The above will only remove the main body of the app but not its dependencies in case there are other packages relying on those dependencies!!.
This can also be done via Synaptic by opening Synaptic and typing the name of the app in search and right click it and mark it for complete removal!.
Hey, this is where Java removal went wrong (I think)!
So now I can either mess around downloading Synaptic ... or I can try to find instructions for manual commands to remove dependencies (I think).
I'm sure this is heaps easier once you know what you're doing. But it's a little weird at first.
