## 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 free repos.

```bash
sudo apt-get update
sudo apt-get install firmware-amd-graphics
```
### 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.

```bash
sudo apt-get update
sudo apt-get install dirmngr
```

### Intel WiFi drivers

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

```bash
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.

#### Installing MongoDB on Debian Stretch

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

# Add the Debian 8 repo
echo "deb http://repo.mongodb.org/apt/debian jessie/mongodb-org/3.6 main" | sudo tee

# Download libssl1.0.0 deb file and install
TEMP_DEB="$(mktemp)" &&
wget -O "$TEMP_DEB" 'security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb7u3_amd64.deb' &&
sudo dpkg -i "$TEMP_DEB"
rm -f "$TEMP_DEB"

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

### PulseAudio

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

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