I just got a VPS on DigitalOcean and put Ubuntu 13.10 on it. I'm trying to setup PostgreSQL for my Rails app. I inserted deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main in /etc/apt/sources.list.d/pgdg.list, then I tried with deb http://apt.postgresql.org/pub/repos/apt/ saucy-pgdg main and deb http://apt.postgresql.org/pub/repos/apt/ lucid-pgdg main (obviously ran sudo apt-get update && sudo apt-get upgrade) but I keep getting this message when running sudo apt-get install postgresql-9.3 pgadmin3:
The following information may help to resolve the situation:
The following packages have unmet dependencies:
postgresql-9.3 : Depends: postgresql-client-9.3 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
The problem is that even if I try apt-getting postgresql-client-9.3 it tells me I need another package:
The following packages have unmet dependencies:
postgresql-client-9.3 : Depends: libpq5 (>= 9.3.2) but 9.1.11-0ubuntu0.13.10 is to be installed
E: Unable to correct problems, you have held broken packages.
And after that, it keeps telling me to install libpq5, which it will not let me install.
Any help with this would be much appreciated.
Thanks!
I know this does not really answer your question but I would re-install Ubuntu with Ubuntu 12.04 LTS and you will have zero issues to install Postgresql 9.3. Rule of thumb is: if you get stuck with installation tasks you are asking for way more trouble when in production.
Just my oppinion but followed this advice with everything I install. Running dozens of clustered postgresql servers myself.

I have some problems following the tutorial "http://wiki.ros.org/Industrial/Tutori...". I have installed ROS Melodic and i want to use an slave ethercat like the "IO rack: EtherCAT Couper, 8 DI, & 8DO (all Beckhoff)" but different brand (Omron), and when i try to follow the step 1: Install OROCOS toolchain for ROS it return a error when i follow the tutorial "http://wiki.ros.org/orocos_toolchain" and execute the command "rosdep install orocos_toolchain" the error is the next: ERROR: Rosdep cannot find all required resources to answer your query Missing resource orocos_toolchain.
I use ROS 1 Distro: melodic SO: Ubuntu 18:04
Someone can i help me, please. I was searching another ways to install OROCOS toolchain but i didn't have success.
Most of the readily available documentation for installing / using Orocos is out of date. For example, that page you were at is (at timeof writing) 6 years old, for an end-of-life distro.
The up-to-date info is on their github and website (The website, for you right now, is probably less useful, but this page still is). Respectively, you should now install that fat stack as sudo apt install ros-melodic-rtt-ros-integration, aka install from binary sources. Make sure to pay careful attention to Building ROS-Based Orocos Components, because they have their own system which changes the CMake process. There's also other packages that they/others keep from other stacks, you can see the whole list by trying to autocomplete apt install ros-melodic-rtt-
To perform a software development task, I need to be sure I have a clean GnuPG Tools stack installed using Homebrew, but I seem to have accumulated some packages that look redundant. How do I install a full GnuPG Tools stack using Homebrew, without ending up with redundant (and possibly conflicting) packages?
I currently have the following installed
gnupg
gnupg2
gpg-agent
gpgtools (as a cask)
Do I need all of these? Can I prune or remove some of them?

I would like to update my version of ImageMagick. I originally installed ImageMagick with...
sudo apt-get imagemagick
Current Version:
myapp$ convert -version
Version: ImageMagick 6.7.7-10 2014-03-06 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC
Features: OpenMP
Location:
myapp$ which convert
/usr/bin/convert
System: Ubuntu14.04 / Apache2.47 / Passenger 4.0.5.5 / Rails 4.1.1 / Ruby 2.1.5
I do not have brew installed. What is the advised way to update?
If you just want to install the latest version from the Ubuntu sources, use
sudo apt-get install --reinstall imagemagick
But it seems that your version is already the current one for Ubuntu 14.04. Upgrading to a newer Ubuntu version would also lead to a newer imagemagick package, see http://packages.ubuntu.com/wily/imagemagick
Alternatively, you can try a version that has been built for a later Ubuntu release, see e.g. https://launchpad.net/ubuntu/wily/+package/imagemagick. Download the deb-file suited for your machine architecture, and install it with
sudo dpkg -i filename.deb
apt-get install -f
However, it is not guaranteed by the Ubuntu developers that this mixing of packages for different Ubuntu versions will work well. But since this is only a single package, there is a good chance that it will work well.
Finally, you can also build it from the upstream sources, see
https://askubuntu.com/questions/267746/how-can-i-install-the-latest-upstream-version-of-imagemagick-without-compiling

I am trying to have a modern docker.io version 1.5+ installed on a CentOS 7 64bit system.
The default docker.io that comes with the yum servers is 1.3.2, and
this version is too old for some of the docker.io features I need, e.g.
(install local docker registry on centos 7)
Details of the system:
docker --version
Docker version 1.3.2, build 39fa2fa/1.3.2
System:
cat /etc/centos-release
CentOS Linux release 7.0.1406 (Core)
uname -a
Linux hostname 3.10.0-123.20.1.el7.x86_64 #1 SMP Thu Jan 29 18:05:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Any ideas how to install a modern docker.io 1.5+?
Please see the official user guide on installing the latest version of Docker on CentOS
At the very start it says: "While using a package is the recommended way of installing Docker, the above package might not be the current release version. If you need the latest version, you can install the binary directly."
This tells you how to do that: https://docs.docker.com/installation/binaries/
Basically:
check your dependencies
download the binary: wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O docker
run the daemon: sudo ./docker -d &
Now you're good to go.
Here is what I did:
Add a repo to yum using this command
sudo vi /etc/yum.repos.d/cbs.repo
and with this contents:
[virt7-testing]
name=virt7-testing
baseurl=http://cbs.centos.org/repos/virt7-testing/x86_64/os/
enabled=1
gpgcheck=0
Start yum using Applications -> System Tools -> Software
Search for Docker
Note that docker 1.5.x is available for install.
If Docker 1.3.2 is installed, uninstall it by unchecking it and clicking apply.
Click the check box next to Docker 1.5.x and click apply.
Test that the install was successful by running docker --version from command line.

I've just recently switched to a Mac from Ubuntu. I was disappointed that mac doesn't have the convenient sudo apt-get in Ubuntu. I've heard that I should use homebrew but I'm not exactly sure what homebrew or macports does?
MacPorts is the way to go.
Like #user475443 pointed, MacPorts has many many more packages. With brew you'll find yourself trapped soon because the formula you need doesn't exist.
MacPorts is a native application: C + TCL. You don't need Ruby at all. To install Ruby on Mac OS X you might need MacPorts, so just go with MacPorts and you'll be happy.
MacPorts is really stable, in 8 years I never had a problem with it, and my entire Unix ecosystem relay on it.
If you are a PHP developer you can install the last version of Apache (Mac OS X uses 2.2), PHP and all the extensions you need, then upgrade all with one command. Forget to do the same with Homebrew.
MacPorts support groups.
foo#macpro:~/ port select --summary
Name Selected Options
==== ======== =======
db none db46 none
gcc none gcc42 llvm-gcc42 mp-gcc48 none
llvm none mp-llvm-3.3 none
mysql mysql56 mysql56 none
php php55 php55 php56 none
postgresql postgresql94 postgresql93 postgresql94 none
python none python24 python25-apple python26-apple python27 python27-apple none
If you have both PHP55 and PHP56 installed (with many different extensions), you can swap between them with just one command. All the relative extensions are part of the group and they will be activated within the chosen group: php55 or php56. I'm not sure Homebrew has this feature.
Rubists like to rewrite everything in Ruby, because the only thing they are at ease is Ruby itself.
Homebrew and macports both solve the same problem - that is the installation of common libraries and utilities that are not bundled with osx.
Typically these are development related libraries and the most common use of these tools is for developers working on osx.
They both need the xcode command line tools installed (which you can download separately from https://developer.apple.com/), and for some specific packages you will need the entire xcode IDE installed.
xcode can be installed from the mac app store, its a free download but it takes a while since its around 5GB (if I remember correctly).
macports is an osx version of the port utility from BSD (as osx is derived from BSD, this was a natural choice). For anyone familiar with any of the BSD distributions, macports will feel right at home.
One major difference between homebrew and macports; and the reason I prefer homebrew is that it will not overwrite things that should be installed "natively" in osx. This means that if there is a native package available, homebrew will notify you instead of overwriting it and causing problems further down the line. It also installs libraries in the user space (thus, you don't need to use "sudo" to install things). This helps when getting rid of libraries as well since everything is in a path accessible to you.
homebrew also enjoys a more active user community and its packages (called formulas) are updated quite often.
macports does not overwrite native OSX packages - it supplies its own
version - This is the main reason I prefer macports over home-brew, you
need to be certain of what you are using and Apple's change at
different times to the ports and have been know to be years behind
updates in some projects
Can you give a reference showing that macports overwrites native OS X
packages? As far as I can tell, all macports installation happens in
/opt/local
Perhaps I should clarify - I did not say anywhere in my answer that macports overwrites OSX native packages. They both install items separately.
Homebrew will warn you when you should install things "natively" (using the library/tool's preferred installer) for better compatibility. This is what I meant. It will also use as many of the local libraries that are available in OS X. From the wiki:
We really don’t like dupes in Homebrew/homebrew
However, we do like dupes in the tap!
Stuff that comes with OS X or is a library that is provided by
RubyGems, CPAN or PyPi should not be duped. There are good reasons for
this:
Duplicate libraries regularly break builds
Subtle bugs emerge with duplicate libraries, and to a lesser extent, duplicate tools
We want you to try harder to make your formula work with what OS X comes with
You can optionally overwrite the macosx supplied versions of utilities with homebrew.
Currently, Macports has many more packages (~18.6 K) than there are Homebrew formulae (~3.1K), owing to its maturity. Homebrew is slowly catching up though.
Macport packages tend to be maintained by a single person.
Macports can keep multiple versions of packages around, and you can enable or disable them to test things out. Sometimes this list can get corrupted and you have to manually edit it to get things back in order, although this is not too hard.
Both package managers will ask to be regularly updated. This can take some time.
Note: you can have both package managers on your system! It is not one or the other. Brew might complain but Macports won't.
Also, if you are dealing with python or ruby packages, use a virtual environment wherever possible.
By default, Homebrew installs packages to your /usr/local. Macport commands require sudo to install and upgrade (similar to apt-get in Ubuntu).
For more detail:
This site suggests using Hombrew: http://deephill.com/macports-vs-homebrew/
whereas this site lists the advantages of using Macports: http://arstechnica.com/civis/viewtopic.php?f=19&t=1207907
I also switched from Ubuntu recently, and I enjoy using homebrew (it's simple and easy to use!), but if you feel attached to using sudo, Macports might be the better way to go!
