MKRhere/wiki

A personal repository for common problems and solutions.

I created this repo so that I don't have to go back and lookup solutions to problems I've already encountered. Feel free to use this repo if it solves your own problems, and raise an issue if you think something can be less hacky or retarded.

Debian GNU/Linux

AMD Radeon drivers

This package contains the binary firmware for AMD/ATI graphics chips supported by the radeon, amdgpu and r128 drivers, not included in the official ISO.

sudo apt-get update
sudo apt-get install firmware-amd-graphics

Crystal

To install Crystal, you will need to add their apt repository. Their setup.sh script helps simplify this.

⚠️ Needs dirmngr to get authentication keys

curl https://dist.crystal-lang.org/apt/setup.sh | sudo bash
sudo apt-get install build-essential
sudo apt-get install crystal

dirmngr

dirmngr is a server for managing and downloading OpenPGP and X.509 certificates, as well as updates and status signals related to those certificates. For OpenPGP, this means pulling from the public HKP/HKPS keyservers, or from LDAP servers. For X.509 this includes Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol updates (OCSP). It is capable of using tor for network access.

sudo apt-get update
sudo apt-get install dirmngr

Erlang

Installing erlang from erlang-solutions:

wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb

sudo apt-get update

# Install one of the following

# Install erlang
sudo apt-get install erlang
# or install esl-erlang - includes the Erlang/OTP platform and all of its applications
sudo apt-get install esl-erlang

Intel WiFi drivers

Intel WiFi drivers are not included in the Debian official repos. They are only available from non-free repo.

echo "deb http://httpredir.debian.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get install firmware-iwlwifi

MongoDB

MongoDB doesn't have official packages for Debian Stretch at this moment, so we'd have to install from the Jessie repository which will throw an error saying the dependency libssl1.0.0 will not be satisfied.

MongoDB has Debian Stretch packages now!

# Get signing keys
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

# Add the Debian Stretch repo
echo "deb http://repo.mongodb.org/apt/debian stretch/mongodb-org/3.6 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list

# Install mongodb
sudo apt-get update
sudo apt-get install mongodb-org

nodejs

nodejs apt repository is several years behind, so add nodesource repos. nodejs 9.x (current version)

# Using Debian
sudo su
curl -sL https://deb.nodesource.com/setup_9.x | bash -
apt-get install -y nodejs

Installing and using nvm nvs

You may need to use multiple node versions on the same machine. nvm will be very useful in this case. nvs is a much better, cross-platform implementation.

export NVS_HOME="$HOME/.nvs"
git clone https://github.com/jasongin/nvs "$NVS_HOME"
. "$NVS_HOME/nvs.sh" install

PulseAudio

Had an issue on Debian Stretch on my Dell PC where pulseaudio daemon won't autostart. This solved the problem each time:

pulseaudio --start
sudo killall -9 pulseaudio
sudo systemctl --user enable pulseaudio.socket
pulseaudio --start

Peek

Peek is a GIF recorder for Linux.

There are no official Debian packages, yet, but you can easily create your own .deb package for Peek. First, install the build dependencies:

sudo apt install cmake valac libgtk-3-dev libkeybinder-3.0-dev libxml2-utils gettext txt2man

Then build Peek and package it:

git clone https://github.com/phw/peek.git
mkdir peek/build
cd peek/build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DGSETTINGS_COMPILE=OFF ..
make package

This will create the package peek-x.y.z-Linux.deb (where x.y.z is the current version). You can install it with dpkg:

sudo dpkg -i peek-*-Linux.deb

RabbitMQ Server

Installing RabbitMQ Server on Debian Stretch fails because the dependent packages erlang-nox and esl-erlang on Debian repos are slightly outdated. Hence, follow these instructions:

Install Erlang first.

# Add RabbitMQ repo from bintray to sources, but don't install it yet
echo "deb https://dl.bintray.com/rabbitmq/debian stretch main" | sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list
sudo apt update

# Try installing erlang-nox
sudo apt-get install erlang-nox

# You might get these errors:
# erlang-nox : Depends: erlang-diameter but it is not going to be installed
#              Depends: erlang-eldap but it is not going to be installed
# If you do so, try this:
sudo apt-get install erlang-diameter erlang-eldap
# Now this should install properly:
sudo apt-get install erlang-nox

# Now actually install RabbitMQ:
sudo apt-get install rabbitmq-server

RabbitMQ Server should have automatically started by now, but if it is not, run rabbitmq-server start (sudo if required).

_MISC

Useful Linux commands
  • Information about graphic card:
    • sudo lspci -v -s 01:00.0
    • inxi -Gx
  • List all shell commands available compgen -c (use with grep?)
