We’re now going to clean up disk space on the VM so when we package it into a new Vagrant box, it’s as clean as possible. First, remove APT cache

$ sudo apt-get clean

Then, “zero out” the drive (this is for Ubuntu):

$ sudo dd if=/dev/zero of=/EMPTY bs=1M

I recently added 2 factor authentication to my GitHub account (and you should too!). However, when I went back to the command line, I could not longer log-in to my account! After doing some searching, it turns out that, with 2FA turned on, you no longer use your password on the command line. Instead, you need to use a personal oauth token. Generating one is super easy, but I wish I had figured this out before hand to save myself the headache of anxiously Googling!

Here are the steps to creating your personal access token:

1. Log into GitHub and access your account settings
2. Select the “Applications” tab on the left-hand navigation
3. Under “Personal Access Tokens” click “create new”
4. Enter a description for your token (so you can keep track and revoke them individually later, should you have a security breach)
5. Copy the token (40 characters long) and use that as your password on the command line.

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

Solution

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install --reinstall base-files=6.5ubuntu6.7+elementary8~ubuntu0.2.1

Error was related to /etc/os-release and /etc/lsb-release. The files looked like this before:

I have marked with a * those which I think are absolutely essential
Items for each section are sorted by oldest to newest. Come back soon for more!

BASH
* In bash, 'ctrl-r' searches your command history as you type
- Input from the commandline as if it were a file by replacing 
  'command < file.in' with 'command <<< "some input text"'
- '^' is a sed-like operator to replace chars from last command 
  'ls docs; ^docs^web^' is equal to 'ls web'. The second argument can be empty.
* '!!:n' selects the nth argument of the last command, and '!$' the last arg
