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
gpg -a --export ...

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.

All the configuration is on the SD card.
There is no factory reset option.
You will have to reflash the SD card to get back to the original position.

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
sudo chgrp -R staff /usr/local/go

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:/...

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-...

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.

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 several 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:
apt-get update && apt-get dist-...

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:
Clozure CL (CCL), 32bit, fast/compact native code compiler
SBCL, fast native code compiler
Embedded Common Lisp (ECL), uses a C compiler for code generation
GNU CLISP, small footprint due ...

If you are running raspbian: sudo apt-get install midori

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.

Running the command
gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553
didn't work for me. gpg baild out with
gpgkeys: key 8B48AD6246925553 can't be retrieved
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
I managed to get it to work using
sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 8B48AD6246925553

'Mono' is a toolset and C# used to create “.NET” compatible programs based on Linux, and the resulting binaries are fully compatible with Microsoft.NET.
start from the Basic programs given in the link here which will definitely help you to understand ´mono´ better.
In Addition I have also used the documentation from the mono developers this which was very ...

The answer marked as correct is in fact outdated, and in a problematic way: rpi-update will update the firmware to the latest published version, which has to be considered "not stable". So following the recipe given you might end up with an unstable system (has happened to me ;) ).

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:
Get:4 http://ftp.debian.org jessie-backports/main armhf Packages [690 kB]
Get:5 ...

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. ...

Welcome to the world of Raspberry Pi! Fortunately, the operating system on a Raspberry Pi is typically Linux based, and I assume this is the same for you. If I am understanding your question correctly, then you want to reinstall a browser onto your Raspberry Pi without having to reflash the whole OS. If so, just run:
sudo apt-get install chromium-browser

Installing Oracle Java 7 JDK (but not JRE) hard-float for RPi is now as stunningly easy as:
sudo apt-get update && sudo apt-get install oracle-java7-jdk
(source)
I used to go through the old processes that were linked above, but since they easyfied it, now I just do this.

dd command, when used correctly, OVERWRITES all partition information along with the partition formats and everything else you might put on SD card. therefore, it does not matter, how SD card was formatted because it's going to be overwritten anyway.

The RPi 2 is backwards compatible with almost all software. I would recommend a full upgade though as it should give you the best performance. While we can run ARM6 code, ARM7 is better.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install raspberrypi-ui-mods (for the new desktop interface)
Then do a restart with sudo ...

I chose x64 for phone
Nope. The pi is not an x86-64 machine. Microsoft has not released a version for the pi yet, but has expressed the intention of doing so. [Later: They have now, follow that same link.]
In other words, you will just have to wait. Note there will likely not be a GUI desktop; it will be some sort of headless "embedded" OS.

What I did was sudo nano /etc/apt/sources.list and added the line deb http://cran.rstudio.com/bin/linux/debian jessie-cran3/
Beware that binary packages from there, such as the R interpreter itself, will only work on specific architectures, presumably at least x86 and x86_64.
But you would need one compiled for ARMv6. If you are using a Pi 2 you could also ...

The answers referencing Mono are largely correct, but I would recommend as an alternative checking out .NET Core instead. .NET Core supports Raspbian as a deployment target. For more detailed information, check out the blog entry at https://blogs.msdn.microsoft.com/david/2017/07/20/setting_up_raspian_and_dotnet_core_2_0_on_a_raspberry_pi/, but to chunk out ...

You haven't mentioned any hardware customisation, so assuming the hardware is standard and it's just your code you need to copy, you could build an image and use an SD duplication service like this (first hit on google) http://www.diskcopy.com/product-info/custom-sd-cards
Then just ship 'stock' raspberry Pi's with your SD cards.
