Can I get a tip for what I am doing wrong trying to install VOLTTRON on an ubuntu tower?
When I git clone the repo I run into this issue.
git clone https://github.com/VOLTTRON/volttron
I just made a git gist since the tracback is too big for stack over flow. Its on the python3 bootstrap.py part of the install
It looks like you may not have installed all of the required system dependencies; see: https://volttron.readthedocs.io/en/latest/setup/VOLTTRON-Prerequisites.html#volttron-prerequisites
You should get the g++ compiler as part of the build-essential package.

I was watching this, and, as you can see, the first command I am told to put in is:
sudo apt-get install python-setuptools
When I do this, it outputs:
sudo: apt-get: command not found
I have no idea why this is the case.
How can I resolve this so I am following the tutorial correctly?
Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.
This command would be:
brew install python
Use Homebrew to install packages that you would otherwise use apt-get for.
The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:
Type the following in your Mac OS X terminal:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After that, usage of Homebrew is brew install <package>.
One of the prerequisites for Homebrew are the XCode command line tools.
Install XCode from the App Store.
Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.
Background
A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.
Alpine based systems use apk.
Warning
As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:
Setting an environment variable:
Open your favorite environment variable editor.
Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
Close the file, and either restart the terminal or source ~/.bash_profile.
Running the following command:
brew analytics off
the analytics status can then be checked with the command:
brew analytics
As Homebrew is my favorite for macOS although it is possible to have apt-get on macOS using Fink.
MacPorts is another package manager for OS X:.
Installation instructions are at The MacPorts Project -- Download & Installation after which one issues sudo port install pythonXX, where XX is 27 or 35.
Conda can also be used as package manager. It can be installed from Anaconda.
Alternatively, a free minimal installer is Miniconda.
apt-get command is only available on Debian or Debian-based Linux distributions (such as Ubuntu, Linux Mint, Kali). It is not accessible on macOS. Alternatively, you can use package managers like Homebrew, MacPorts, and Nix. You can find equivalent commands for each as follows
brew install package_name
sudo port install package_name
nix-env -i package_name
Before installing above package managers, you need to install XCode first. Follow the operation instructions from this guide How to Fix "sudo apt-get command not found" Error on Mac Terminal.
Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...
For example,
curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz
I am new in json and I don't know how to use but I found compare to XML json is better so, I am learning json in C programming in Ubuntu 14.0LTS.
I followed https://linuxprograms.wordpress.com/2010/05/20/install-json-c-in-linux/.
In this link, I installed libjson0 with the help of first command but when I installed libjson – debug symbols package with the help of second command which is mentioned in link then showing "E: Unable to locate package libjson0-dbg".
Also I gone through https://github.com/json-c/json-c. After cloning moved to json-c directory, in json-c directory I did sh autogen.sh then showing "autogen.sh: 2: autogen.sh: autoreconf: not found".
Why autoreconf is not works ? When I installed CppUTest and other stuffs then it works.
I also install build-essential which found in google for above problems but it can't works for me.
How can I installed cjson in a proper manner and how to use with the C-programms.
Try below commands:
$ sudo apt-get install libjson-glib-1.0-0 libjson-glib-1.0-0-dev
If you want to debug your programs and see the various steps of serializing/deserializing you can also install the libjson-glib – debug symbols package
$ sudo apt-get install libjson-glib-1.0-0-dbg
For documentation related to json-glib, you must install the following package
$ sudo apt-get install libjson-glib-1.0-0-doc
This documentation will then be available in file:///usr/share/gtk-doc/html/json-glib/index.html
Maybe your problem is related with the path.
The library is installed correctlly but you have tot tell the system where. Here a post on how to do it in Ubuntu How to set the environmental variable LD_LIBRARY_PATH in linux
While installing CodeLite IDE in Ubuntu following error occurs.
Any idea?
ERROR:
The following packages have unmet dependencies:
codelite : Depends: libjbig0 but it is not installable
Depends: liblzma5 (>= 5.1.1alpha+20120614) but 5.1.1alpha+20110809-3 is to be installed

Depends: libpangocairo-1.0-0 (>= 1.14.0) but it is not installable
E: Unable to correct problems, you have held broken packages.
I had a similar problem. You may need to check your version of Ubuntu, and that you've added the correct repositories. If this is the problem, then the fix is very simple!
Firstly, check your version of Ubuntu. From terminal you can do this with the command lsb_release -a. The important part, for our purpose, is the codename. I'm using Ubuntu 13, aka "saucy".
Now let's look at the multiverse repository that you added. From the terminal you can do this with sudo gedit /etc/apt/sources.list. Go down to the end of the file, and you should see something like:
## This software is not part of Ubuntu, but is offered by third-party
## developers who want to ship their latest software.
deb http://repos.codelite.org/ubuntu/ saucy universe
Make sure that your version has your ubuntu codename (in my case 'saucy'). The example code on the website is for Ubuntu 14, and so I wrongly had a 'trusty' source here. Edit the line so that it is correct for your version of Ubuntu, and then save and close the file.
Lastly, you'll need to update your repos so that the change goes through. From the terminal, run sudo apt-get update. All being well, you should now be able to sudo apt-get install codelite without the errors.
My problem was caused by too much cutting-and-pasting code from the codelite website. I followed exactly the same page as you did, and their example code is for people with Ubuntu trusy (14).
You will need to be more specific on how you tried to install codelite.
The official Debian repository manages an ancient version of codelite which we (the codelite team) do not support.
In order to get the most up-to-date version (that we support) please install it from codelite's official website (select the Download at menu at the top)
Before installing, make sure you delete the folder ~/.codelite (incase you are upgrading)
Also, the official Debian installer is split into 2 pakacges codelite and codelite-plugins make sure you purge them both before installing codelite from our repository
I'm the author of Howto install the latest codelite in Ubuntu - EuroBytes. I have tested the latest codelite on Trusty.
If you still have issues with codelite, remove like so: sudo apt-get purge codelite
Note that the dependencies links are dead. But, i managed to install it anyways:
codelite 6.1 on Ubuntu Trusty Thar 14.04.
Image from: Howto install the latest codelite in Ubuntu - EuroBytes
Install like so:
sudo apt-add-repository "deb http://repos.codelite.org/ubuntu/ $(lsb_release -sc) universe"
sudo apt-key adv --fetch-keys http://repos.codelite.org/CodeLite.asc
sudo apt-get update
sudo apt-get install codelite wxcrafter
Feel free to contact me here or on my site, for any issues you may have.

I'm trying to install V4L2 on Ubuntu 10.04 (lucid) that require the xlibs-devinstalled. I tried: sudo apt-get install xlibs-dev but it returns:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package xlibs-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package xlibs-dev has no installation candidate
then I tried:
First attempt: attemp:sudo apt-get install xorg-dev;
Second attemp: sudo apt-get update and sudo apt-get upgrade;
All failed. same install xorg-dev,updated and upgraded my packages, can't to install the xlibs-dev library. how to fix this? thanks in advance.
The command
apt-cache search xlib dev
suggest you to
aptitude install libx11-dev
And your distribution might have V4L2. Consider installing the v4l2ucp package...
PS. There is no s letter in xlib because it is one library, not several!
I installed opencv2.3 on ubuntu by first adding the ppa and the doing apt-get install
$ sudo add-apt-repository ppa:gijzelaar/cuda
$ sudo add-apt-repository ppa:gijzelaar/opencv2.3
$ sudo apt-get update
$ sudo apt-get install libopencv-dev
I am developing on Eclipse and my programs work. I have this one problem though, while following an ebook. I cannot find the /opencv/samples folder in my system. I did a unix directory search to no avail.
Also, in Synaptic Package Manager I find that the opencv packages are not marked green, ie they're not installed. However I have written and executed opencv codes on my machine.
What is the reason for this?
It seems you have installed binary OpenCV package while the samples are (most likely) included only to source package.
