Universal Netboot Installer

The first thing I did when I received my new Asus F6Ve-B1 was download Ubuntu 9.04 and ready myself for a clean installation of a decent operating system. I burnt the ISO, rebooted my PC, and entered the Ubuntu installation menu. Shortly after I was presented with a screen full of errors.

[ 57.764316] Buffer I/O error on device sr0, logical block 22

This means that the CD cannot be read. Either because of faulty or misconfiguration hardware or faulty media. After a quick Google search, there appeared to be several solutions. The most popular ones being “Try a new CD ROM drive” and “Burn your ISO at a lower speed and verify the md5 signature.” I opted for neither of these solutions, an instead did a USB install. A very useful piece of software to aid in this process is UNetbootin.

UNetbootin can create a bootable Live USB drive, or it can make a “frugal install” on your local hard disk if you don’t have a USB drive. It can load distributions by automatically downloading their ISO (CD image) files, or by using existing ISO files, floppy/hard disk images, or kernel/initrd files, for installing other distributions.

This is a must have piece of software for your toolbox!

Note that the MySQL client library is not bundled anymore!

Unable to get PHP configured to my specifications using the Ubuntu repositories, I decided to install it from source. However, I kept getting the error:

Note that the MySQL client library is not bundled anymore!

Not wanting to install MySQL from source, I found a package in the Ubuntu repositories that installed the necessary library files.

sudo apt-get install libmysqlclient15-dev

After I installed that package, PHP was able to install successfully.

Slow connection to Ubuntu repositories

While attempting to get a fully functional LAMP stack running on my Ubuntu install, I opted to use the repositories for some necessary libraries. The first package I installed was approximately 20MB and it took about three hours. While it was downloading (since I had some spare time), I checked my internet connection. I soon found out that it wasn’t my ISP since I was getting 12Mb/s down. I also scanned the Ubuntu forums for any sign of server maintenance that could be causing the slowness. I didn’t find anything. I then tried changing the repository download location:

System->Administration->Synaptic Package Manager from there Settings->Repositories. From the “Download from” drop down, select “Other.” Click on “Select Best Server” will ping all of the repository locations and select the location with the best ping.

That didn’t help either. After many fruitless attempts I narrowed the fault down to my router. I upgraded its firmware and that fixed it!
