Ubuntu Grub Fails to Install on RAID Array

Ubuntu Grub RAID Issues

Grub Fails To Install on RAID Array

If grub fails to install on your RAID array in any version of Ubuntu, do NOT disable your BIOS RAID! The correct solution is at this blog entry. I'll summarize it below.

At the stage of the install where it is attempting to install GRUB it will detect as

/dev/mapper

This is incomplete! That's why the GRUB install fails.

You need the actual name of the RAID array to install to. So during that step, press ctrl+alt+F2 to drop to a busybox terminal, then enter

ls -l /dev/mapper

Pick out the name of your array from the list shown, then press ctrl+alt+F1 to switch back to the install (you can switch back and forth as much as you like with no problems) and enter it in the field as

/dev/mapper/{your array name}  

Then GRUB installs perfectly and you're ready to go, with a proper BIOS RAID array intact.

System Won't Boot After Grub Failed to Install

If your system will no longer boot because you skipped installing or updating grub, you need to download an Ubuntu version that does support RAID, boot from the LIVE CD, drop to a terminal, and then run:

ls -l /dev/mapper
sudo grub-install /dev/mapper/{ARRAY_NAME_HERE}

Setting Up RAID Array During Ubuntu Install

If you are configuring a BIOS RAID array for the first time on Ubuntu, you should create a 1MB boot partition.  Its partition type is "boot".  If you do this, grub will always try to install there and will succeed every time without failing when upgrading or reinstalling grub.

Geany PHP Beautifier

PHP Beautifier Support for Geany

Geany is by far one of the best text editors I have come across that works on both Windows and Linux.  It is also one of the most aesthetically pleasing editors to look at right out of the box.  I do a lot of PHP scripting, and as such, it is nice to have a "beautifier" script that will automatically format my code for me so that it looks nice.  Geany can also call the php executable and check your script syntax. You can achieve both of these features by installing both PHP for Windows and the PHP Beautifier PEAR addon.   

Install PHP for Windows:

If you code your PHP scripts in Windows, you'll want to use syntax checking and the PHP_Beautifier script.  To do so, you must install the PHP5 Windows package, which includes the main PHP binaries.

To get the files, download the latest version of PHP 5.3.

Extract the contents of the archive to "C:\php5"

Go into C:\php5 and rename "php.ini-development" to "php.ini".

PHP BEAUTIFIER WILL NOT WORK ON ANY NEW VERSION OF PHP FROM 5.4.X and UP!

Install PEAR for Windows:

PHP_Beautifier relies on PEAR functionality.  To install pear, save this file using a browser and place it in the "C:\php5" directory.  

Start command prompt, change directory into "C:\php5", and run the phar script:

C:\
cd C:\php5
php go-pear.phar

Install everything and keep default options.

Install PHP_Beautifier:

Now, install PHP Beautifier by running the following commands:

pear install PHP_Beautifier

Integration in Geany:

For PHP Syntax Checking:

In Geany, click on "Edit" in the menu bar and choose "Preferences".

In the "General" and "Startup" tabs, under the "Paths" section, paste "C:\php5" (without the quotes) into the "Extra plugin path:" field.

For PHP Beautifier:

Start the Geany text editor program.  Open a PHP script file.

Select the code you want to format, right click on the selected text, and choose "Format" –> "Send Selection to" –> "Set Custom Commands".

For command, use the following:

php C:\\php5\\php_beautifier -s4 -l "ArrayNested() NewLines(before=T_COMMENT:for:switch:foreach:T_CLASS:function:T_CLOSE_TAG,after=T_ENDIF:T_CLOSE_TAG:T_OPEN_TAG:T_ENDSWITCH:T_ENDWHILE:T_ENDFOR:T_ENDFOREACH)"

For "Label", use "PHP Beautifier"

Hit OK.

Now, select the code you want to format, right click on the selected text, and choose "Format" –> "Send Selection to" –> and pick "PHP Beautifier".  The code should now be formatted using the options specified in the command line arguments above.

For more filter options and commandline parameters, please read this PHP_Beautifier document.

Make MATE or GNOME2 Look Like Windows XP Using the Luna Theme

If you want your Linux installation to look like the original theme used in Windows XP, you can do that! This guide will walk you through the process of easily making any MATE or GNOME2 Desktop Environment look like the Windows XP GUI. The Luna Theme can be downloaded here and installed using our simple installation script. If you already have MATE installed or are already running GNOME2, skip to the Luna Theme install instructions.

Install MATE on Ubuntu:

Run the below commands for your matching Ubuntu version in a terminal to install MATE.  To find out which version of Ubuntu you're running, use this command:

lsb_release -a

For Ubuntu 12.04:

sudo add-apt-repository "deb http://packages.mate-desktop.org/repo/ubuntu precise main"
sudo apt-get update 
sudo apt-get --yes --quiet --allow-unauthenticated install mate-archive-keyring 
sudo apt-get update
sudo apt-get install -y mate-desktop-environment

For Ubuntu 14.04:

sudo apt-add-repository ppa:ubuntu-mate-dev/ppa
sudo apt-add-repository ppa:ubuntu-mate-dev/trusty-mate
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y mate-desktop-environment-extras

For Ubuntu 16.04:

sudo add-apt-repository ppa:ubuntu-mate-dev/xenial-mate
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y mate-desktop-environment

For Other Distributions (Distros):

http://wiki.mate-desktop.org/download

Installing the Luna Theme:

Our version of the Luna theme has been converted and ported over to GTK3, so it should work with all newer flavors of Linux running MATE while still working on older Linux installs running GNOME2.To install the Luna Theme which will make Linux look like Windows XP, run the following commands. The theme files will be downloaded and saved in your Downloads directory.

cd ~/Downloads
wget -O linux_xp_luna_theme_install.tar.gz http://dinofly.com/files/linux_xp_luna_theme_install.tar.gz
mkdir Luna
tar -zxvf linux_xp_luna_theme_install.tar.gz -C Luna
cd Luna
sudo rm -rf /usr/share/themes/Luna
rm -rf ~/.themes/Luna
sudo bash install.sh

Next, Right Click on the Desktop, and choose "Change Desktop Background".  Click on the "Themes" tab.  Select "Luna".  Click on the "Background" tab.  If you want the default XP wallpaper set as your background, click on the "Add" button.   Select your "Pictures" folder.  Select "luna_background.jpg".  Click "Open".  Click on "Close" to change it. 

Now, MATE or GNOME2 looks like XP!  Enjoy!  This theme was copied from Ylmf OS 3.0.

PeerGuardian Linux Ubuntu Prerequisites and Install Guide

Saturday, March 24th, 2012

PeerGuardian Installation Guide Ubuntu / Debian

Installing PeerGuardian:

Open a new terminal and install the prerequisites for PeerGuardian Linux but using the following commands:

sudo apt-get install libdbus-1-dev zlib1g-dev iptables libnetfilter-queue-dev libnfnetlink-dev qt4-bin-dbg qt4-dev-tools qt4-bin-dbg g++ libpolkit-qt-1-1 libpolkit-qt-1-dev

Download the latest source of PeerGuardian Linux from:  http://sourceforge.net/projects/peerguardian/files/PeerGuardian%20Linux/

Open a terminal, change to the peerguardian source directory, and run the configure file to generate the makefile.

./configure --sysconfdir=/etc

If you get an error stating that looks like this:

checking for ZLIB... configure: error: Package requirements (zlib) were not met:

No package 'zlib' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables ZLIB_CFLAGS
and ZLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

You'll need to download and compile the source of zlib from  http://www.zlib.net/

To do this, just change to the directory of the extracted zlib folder, run:

./configure
sudo make
sudo make install

Now, go back to the peerguardian source directory, and re-run ./configure

You will not receive this error anymore.  Why does this happen in the first place?  Installing zlib1g-dev should have been enough to satisfy this requirement, but for some reason it doesn't work sometimes and could be a bug.

Errors Post Installation:

BELOW ISSUE (BOTH Bricking your System and Resolv.conf Issue) APPEARS TO HAVE BEEN FIXED IN MAY of 2013
I'm going to leave this here though in case someone needs it.
 

As of 3/17/13, I've noticed that installing Peerguardian Linux from the latest SourceForge source causes a number of serious problems that could brick your Linux install. You must run the following commands after "make install" is completed to avoid running into problems.

If your gksudo or sudo commands no longer work after installing because of a "Unable to copy the user's .Xauthorization file" error message, your .Xauthority file may no longer exist.  To fix this issue, run the following commands:

gksudo synaptic
sudo chown youruser:youruser ~/.Xauthority
chmod 600 ~/.Xauthority

If the above does not work for you, try this:

cd ~
touch .Xauthority
sudo chown youruser:youruser ~/.Xauthority
chmod 600 ~/.Xauthority 

For some reason, the installer also changes the permissions on the tmp system folder.  To fix this, run the following command:

sudo chmod 1777 /tmp

Peerguardian Linux can also break your DNS settings rendering your internet connection useless.  To fix this issue, run the following commands:

sudo nano /etc/resolv.conf

In it, put your router's dns information in. For example:

nameserver 192.168.1.1

Save and close the file.  Everything should be good to go and your system is not hosed from a buggy compilation of Peerguardian Linux
