I have a dell Optiplex 755 usff and I just installed Ubuntu 16.04 on it and I want to install apps on it but outside of the Ubuntu software center. How can I do this and not run into any errors? Also what apps are recommended for a start to ubuntu? I would like java, flash, VNC, Steam, Utilities, and customization apps? (I'm just asking here how can I install applications on Ubuntu without any pre-installed applications and not run into any errors)
This is indeed broad but simply put you install apps outside Ubuntu Software Center by using
.deb file and installing them from the commandline or terminal. The steps are simply:
- Download the file say:
- Open terminal with Ctrl+Alt+t
sudo dpkg -i myapp.deb
Get any dependency errors from
step 3, then do:
sudo apt install -f sudo apt update
- Repeat step 3
Please spend some time reading about Ubuntu in general so you will understand the basics.
You can install apps without using the software center. It does require the use of a terminal, however.
The easiest way if from
apt provides a high-level commandline interface for the package management system. It is intended as an end user interface and enables some options better suited for interactive usage by default compared to more specialized APT tools like apt-get(8) and apt-cache(8).
You can use it like:
sudo apt install vlc
and it will install vlc player for you.
The other method is obtaining the
.deb files, or download links. To download a
deb file, get the URL, and
sudo wget urltodebfile
and then, install with:
sudo dpkg -i debfile.deb
sudo apt install -f
to fix any missing dependencies.
If you're interested:
dpkg is a tool to install, build, remove and manage Debian packages. The primary and more user-friendly front-end for dpkg is aptitude(1). dpkg itself is controlled entirely via command line parameters, which consist of exactly one action and zero or more options. The action- parameter tells dpkg what to do and options control the behavior of the action in some way.
