Device /dev/hda3 not found (or ignored by filtering)

I just created a partition (/dev/hda3) with fsdisk and here is how things look:

when i run 

vgcreate /dev/hda3

i get the following error:

Device /dev/hda3 not found (or ignored by filtering).

Now What? After some Googling i found out that you have to run a “partprobe” command.

partprobe /dev/hda

Now i am able to run the 

vgcreate /dev/hda3

without a problem.

The partprobe command is used i lieu of rebooting the system. It is a command to let the system know that the partition table has changed.

Failed to fetch http://security.ubuntu.com/

Error

Failed to fetch http://security.ubuntu.com/ubuntu/dists/karmic-security/main/binary-amd64/Packages

Solution:

1. Open /etc/apt/sources.list

2. Replace security.ubuntu.com with old-releases.ubuntu.com

So the new link looks like the following:

Can’t init outfile ycsoftware.mp3

Can't init outfile

This error is as Lame as the encoder’s name “Lame encoder”

FIX:

Give the user Apache full permission onto the destination folder.

Try using “/tmp”, if that works, then it is indeed a permission issue.

Can’t locate Plack/Handler/Starlet.pm

Error Messages

Plack::Handler::Starlet ...MISSING

Can't locate Plack/Handler/Standalone/Prefork/Server/Starter.pm in @INC

FAIL Installing Plack::Handler::Starlet failed. See /USER/.cpanm/build.log for details.

Where the heck are the documentations for these modules?

I have tried everything cpanminus, cpan, cpanplus ect… Nothing would work until i did the following:

Navigate to the Perl Directory
(or wherever Perl is located on your system)
cd /usr/local/share/perl/

Within your perl folder there should be a folder called /Plack/Handler/
and within this folder there should be a file called “Starlet.pm” 

/usr/local/share/perl/5.10.0/Plack/Handler/Starlet.pm

if this file is missing, you need to locate within your system or on the internet and copy or move it to that folder.
Mine was located here /USER/.cpan/build/Starlet-0.14-Spf5Vd/lib/Starlet.pm

Run make testdeps again and voila no more error messages:
