Am using a samba share on Ubuntu 16.04 server, and wanted to enable Samba traffic in ufw using sudo ufw allow from 192.168.8.0/24 to any app Samba comment 'allow samba from local' which returned the error "ERROR: Could not find a profile matching 'Samba'".

Cause: I was using the minimal amount of tooling required to use Samba (cifs-tools) on my server, which doesn't include the Samba application file.

Fix: install the samba package... or manually create the file:

sudoedit /etc/ufw/applications.d/samba

Using pyenv seems to be the easiest way apart from a random PPA or finding/downloading/compilign the source myself.

Build dependencies:

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev

Install Pyenv (as the user who will use it, not root):

curl -L https://raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer | bash

Upgraded from Ubuntu 16.04 LTS to 18.04 (pre-release) using dist-upgade
Upon restart CT would not start
Error displayed in Web GUI: command 'systemctl start pve-container@101' failed: exit code 1
SSHd in and manually ran CT with pct start 101:

>root@server:~# pct start 101
Job for [email protected] failed because the control process exited with error code.

0. Preparation

Make sure LXC has more than 12GB, otherwise Unifi fails to start!

1. Follow steps from Ubiquiti site

https://help.ubnt.com/hc/en-us/articles/220066768-UniFi-How-to-Install-Update-via-APT-on-Debian-or-Ubuntu

# for unifi
echo 'deb http://www.ubnt.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list

1. Install acme.sh shell script

git clone https://github.com/Neilpang/acme.sh.git
cd acme.sh
./acme.sh --install

Optionally, set the home dir and/or account info (if already have one).
If was previously using LetsEncrypt's certbot, can probably get account info from /etc/letsencrypt/accounts/acme-v01.api.letsencrypt.org/directory/*/regr.json.

Setup full disk encryption using LVM on LUKS (single drive) with remote SSH for an already setup/running Raspbian stretch system. Using this guide there is no need to connect a screen or keyboard to the rpi at any stage since we will setup remote SSH at the same time (at present no other guides available tell you that this is possible).

1. Backup SD card

To be safe, backup SD card (using another computer is easiest in my case): sudo dd bs=4M if=/dev/<rpi_sdcard> | gzip > rpibackup.img.gz or use my fish shell function.

2. Install LUKS dependencies and reboot

My notes on how I setup OpenVPN server on Edgerouter Lite. Based mostly on this guide from openVPN wiki. This guide assumes easyrsa3 is being used, otherwise substitute whatever the easyrsa2 versions are for the commands below.

This guide will use 3 different machines.

A Public Key Infrastructure (PKI) will be created on each machine:

1. Server - openVPN server (Edgerouter in this case).
1. Client(s) - the device(s) you will be connecting from.
1. CA Server - used to generate and sign certificates for server and clients to use.
