How to fix OwnCloud Key Expired Error

If you get an error like

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://download.opensuse.org  Release: The following signatures were invalid: KEYEXPIRED 1397815516

W: Failed to fetch http://download.opensuse.org/repositories/isv:/ownCloud:/community/xUbuntu_12.04/Release

W: Some index files failed to download. They have been ignored, or old ones used instead.

You simply need to reimport the new key… copy and paste the command below

wget -qO - http://download.opensuse.org/repositories/isv:ownCloud:community/xUbuntu_12.04/Release.key | sudo apt-key add -

How to update django

So i was recently faced with the dilemma of having to update django 1.6.1 to 1.6.2, after a bit of searching I came across a very.. very simple solution

pip install -U Django

Of course this is assuming you installed django… if not you most likely need to uninstall it by deleting the path where it lives.. eg

Python 2.7.5+ (default, Sep 19 2013, 13:48:49) 
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django
<module 'django' from '/usr/local/lib/python2.7/dist-packages/django/__init__.pyc'>
>>>

then

sudo rm -rf /usr/local/lib/python2.7/dist-packages/django/

How to setup a VPS (or Dedicated Server) with Nginx from scratch

In this tutorial we are going to go through the steps of securing the server and configuring Nginx, PHP, Phpmyadmin and MySql.

Step 1. Basic Security

Assuming you have already logged into your server we start by changing the root password to something more secure.

passwd

 

This will prompt you to change the root password, It is recommended to choose something extremely complex as it is your most crucial line of defence against the outside world.

Next, open up the ssh config

vim /etc/ssh/sshd_config

and change the port from 22 to anything between 1025 to 65536, this will prevent our server from being easily spotted by malicious eyes (more…)
