"In normal circumstances there is NEVER a need to run rpi-update as it always gets you to the leading edge firmware and kernel and because that may be a testing version it could leave your RPi unbootable". https://www.raspberrypi.org/forums/viewtopic.php?p=916911#p916911
Even the rpi-update documentation now warns "Even on Raspbian you should only use this ...

Try this answer: No PUbKey Error.
I am not sure but I think you only need the generic debian key here. I tried it on my system and it added ok. Let me know if that resolves it for your use.
So, to be clear, and using the OP as source for the key in the following example:
gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553

I got Teamspeak 3 running using qemu running a x86 Debian squeeze. There is some room for improvement for sure, but for now that's what worked for me. I hope I didn't forget something.
First of all thanks to Dietmar and meigrafd of the raspberry pi forum. Without their work I wouldn't have succeeded.

raspbian package repo contains raspberrypi-bootloader package which contains firmware, kernel and kernel modules that rpi-update downloads. The version is not the latest, but files should be fine and stable. Now it shows a 20130902 version, so it's about 2 months old. The package is installed by default and is updated when a new version arrives in repo.
So ...

[Note: Later in 2013 the Pi Foundation announced Raspbian now ships with Oracle hard-float.]
The oracle 8 preview works for me, thus far. Compiling is slow on the pi, surprise, but the jre seems to run quite fast once it loads. I think bearbin's answer is pretty definitive but if you want a simple way to try oracle:
Download. You get a .tar.gz file, ...

As of Go 1.6 (February 2016), an official ARMv6 package is available for download. So, if your Raspberry Pi has ARMv6 or v7 (see cat /proc/cpuinfo | grep ARM), then just do something like:
wget https://storage.googleapis.com/golang/go1.6.2.linux-armv6l.tar.gz
sudo tar -xzf go1.6.2.linux-armv6l.tar.gz -C /usr/local

There's already a go compiler in, e.g., raspbian, which you can find with apt-cache search golang. This looks to be version 1.0.2.
The site you linked has pre-compiled tarballs of 1.3.3 available for the pi. You just need to download the appropriate one -- it is clearly indicated.
Put the tarball in /usr/local and:
tar -xzf go.1.3.3.linux-arm~multiarch-...

OpenCV is now available in apt-get. You can search for it:
apt-cache search opencv
If you are doing development, just do:
sudo apt-get install libopencv-dev
At the time of this writing, it is OpenCV 2.3

On a B, B+, 2B or 3B you can't do it without something to write the SD card. The only things these models can boot from out of the box is a SD card.
You may well find that you can use a camera or an older smartphone as a card reader (newer smartphones tend to use MTP rather than mass storage, so they are not suitable for this) to write your card.
On a ...

Assuming you're using Raspbian, you need to find out which .deb file you need, and transfer those to your Raspberry Pi, and place them in /var/cache/apt/archives/partial, and then just use the command:
sudo dpkg -i /var/cache/apt/archives/partial/xxxx
where xxxx is the exact name of the .deb file you want to install
If you need to find dependencies, http:/...

Going back to basics, I looked at the installation page for pandas and found that pip install pandas isn't the recommended route on linux systems.
sudo apt-get install python-pandas did the trick.

From looking at the log file I came across the line
INFO: HTTP Listener started: port=8080
java.io.IOException: Failed to start a listener: winstone.ssl.HttpsListener
This tells us that either the port you are using 8080 is in use but you have run netstat and established that it is not listed- so its available and not causing the exception.

For Common Lisp there are quite a few free implementations available. The following are working on the Raspberry Pi or similar ARM-based computers with GNU/Linux:
Free:

SBCL, fast native code compiler
Embedded Common Lisp (ECL), uses a C compiler for code generation

I had to use sudo apt remove docker-ce. The script at get.docker.com runs "$pkg_manager install -y -q docker-ce$pkg_version" so docker-ce is the package, not docker.

Meanwhile the kernel is part of the raspberrypi-kernel-package in Raspbian.
So rpi-update is not needed anymore to update the kernel.
There are two kernels in the package, that means it works on every hardware-version of the Pi (ARMv6, ARMv7 and ARMv8
Just use this fancy one-liner to keep your Pi up-to-date:

In my case a different key ID was missing when I tried to install backports.The answer above +1 also worked on my raspberry pi3 with raspbian jessie. I'm writing this just to make a point that you can install missing keys with the same method. Bash terminal message was this:

All of the above answers are outdated. My answer is not very good, but hopefully avoids the issue of becoming outdated.
The official wiki explains, in detail, how one goes about installing/building a package that is not part of pacman (packer and yaourt as of this date).
Both packer and yaourt are flagged as out of date in AUR. (this may change in the ...

I think you need to clarify what you are trying to achieve, but hopefully this will help.
Firstly, C# is a language. You write programs in C# and these will run on the .NET framework. It is the .NET framework that must be installed on your device for your C# program to run.
Since last year you have the option to install Windows 10 IoT Core on your ...

The manufacture of Raspberry Pi's as far as I am aware is by Element14/Premier Farnell. Originally they were made in China but are now produced in the UK, which is fitting, given the Foundation is a British organisation. You can read more about that here.
In terms of a Pi made for commercial use Element14 have an exclusive Raspberry Pi customization area. ...

As you can see on Raspberry Pi FAQ, the real performance of the Raspberry Pi is something like 300 MHz Pentium 2. There is 256 MB RAM installated on both model A and B. Try to compare this parameters to the parameters of your computer.
