Linux Lite won't let me install *any* software

[gold_finger]

• Installing software on Linux is not done the same way as you may have done in Windows.  Generally, most software you need is in a centralized repository and is easily downloaded and installed from there with a few clicks in a GUI interface or by entering a simple one-line command in a terminal.  Also, programs designed for Windows will not work on Linux, so you can't download and install them.  If there is not a Linux version of a program you want, there is a good chance that there are one or more existing Linux programs that do the same thing.
  
  For Google Chrome, simply go to Menu -> System -> Install Additional Software, then choose it (#2) from the list shown and it will be installed for you.
  
  The Install Additional Software section contains some commonly desired programs for easy installation.  It is NOT a list of all software available, which numbers in the thousands of programs.
  
  The system has a program called Synaptic Package Manager on it that will allow you to install any of the thousands of programs available in the repositories (Menu -> System -> Install/Remove Software.  However, it is most useful only when you already know the names of what you need ahead of time.  For people new to Linux, using a 'Software Center' application is much easier because it displays software with descriptions and screenshots under various common categories.  That is not included in the default LL installation.  You need to install that first before you can use it.
  
  To install a software manager, open Synaptic Package Manager and search for both of these:
  • software-center  (Correction:  this one does not work well in LL.  Do not use.) 
    
  • lubuntu-software-center  (Not 100% sure if this will be problem free in LL.  Backup important data first just in case a reinstall of system ends up being required.)
   
  
  
  Click each of those (exact names above, not listings with other things added to the names) to read a description of the programs.  Both are very similar and either will be fine.  (Correction:  software-center will cause problems, lubuntu-software-center might be okay.)Pick one by clicking the box next to it and select "Mark for Installation".  Then hit the apply button and let it install any other dependent packages if it lists them too.
  
  When complete, you can find it listed under Menu -> System.
  
  
  P.s.
  I would suggest you take a little time to read through the Help Manual (Menu -> Favorites -> Help Manual) to get an idea of how some things work in Linux.  Also see some of the links on this post for additional information:  https://www.freecinema2022.gq/forums/index...opic=273.0.
