Installing Adobe AIR in Fedora 11

So here it goes, I wanted to install twhirl and was required to install Adobe AIR of course, however, I got this error several times.

Sorry, an error has occured.
An error occured while installing Adobe AIR. Installation may not be
allowed by your administrator. Please contact your administrator.

Apparently, I have several dependencies to install. So here are the steps to make it work.

1. Issue the following commands.

su -c "yum install gtk2-devel rpm-devel"

(Its very similar to Ubuntu (if you have used one), that every AIR app you install will have a .deb equivalent, in this case a .rpm.)

2. Download Adobe AIR.

3. Install it by issuing the following commands.

chmod +x AdobeAIRInstaller.bin
su -c "./AdobeAIRInstaller.bin"

4. Now AIR is installed, but mostly will not be able to install via its Adobe AIR Application Installer UI or give you an "Error #5100"; install apps via its terminal command.

Adobe\ AIR\ Application\ Installer /media/Shared/Downloads/twhirl-0.9.2.air

(be sure to explore to the apps directory, rather than changing to its directory)

Now you should have a successfull Adobe AIR installation!

Triple-Boot Ubuntu, Fedora, and Vista

So here, I will share my experience when I did my first triple-boot to give you an idea on where to start.

I used my laptop, with a 80GB hard drive, partitioned it into 1 primary and 1 extended partition, dividing up the extended partition further more. I used Fedora 10, Windows Vista Home Basic, and Ubuntu 9.04 respectively.

Primary Partition #1 (ntfs, 20.00 GiB)
Extended Partition #2 (extended, 36.52 GiB)

Logical Partition #3 (ntfs, 36.52 GiB) – Shared NTFS Partition
Logical Partition #4 (ext3, 8.00 GiB) – Ubuntu
Logical Partition #5 (linux-swap, 1.00 GiB) – Ubuntu Swap
Logical Partition #6 (ext3, 8.00 GiB) – Fedora
Logical Partition #7 (linux-swap, 1.00 GiB) – Fedora Swap

So basically you have 7 partition all in all. One thing to notice is that I've created a swap for each linux distro, it is not necessary to do it because I later found out that both distros use both swaps making my swap a total of 2GB.

Now, I installed Vista first so I wouldn't have a problem later on restoring my GRUB. Next is install Ubuntu, basically you do as you do it on dual boot. Lastly is Fedora, there are 2 options, use Fedora or Ubuntu's GRUB. Each are the same, but I preferred using Ubuntu's GRUB (I didn't install the Fedora's GRUB during its installation). Then you add Fedora's boot partition in Ubuntu's /boot/grub/menu.lst like the following below,

title Fedora Core 10, 2.6.27.5-117.fc10.i686
root (hd0,7)
kernel /boot/vmlinuz-2.6.27.5-117.fc10.i686 ro root=UUID=0a5ed460-5d07-40b1-9ca1-50ff10214c80 rhgb quiet
initrd /boot/initrd-2.6.27.5-117.fc10.i686.img

All in all, your menu.lst should look something like this,

title  Ubuntu 9.04, kernel 2.6.28-11-generic
uuid  df1599f4-12b7-4419-87de-e4c9c27799d4
kernel  /boot/vmlinuz-2.6.28-11-generic root=UUID=df1599f4-12b7-4419-87de-e4c9c27799d4 ro quiet splash
initrd  /boot/initrd.img-2.6.28-11-generic
quiet

title  Ubuntu 9.04, kernel 2.6.28-11-generic (recovery mode)
uuid  df1599f4-12b7-4419-87de-e4c9c27799d4
kernel  /boot/vmlinuz-2.6.28-11-generic root=UUID=df1599f4-12b7-4419-87de-e4c9c27799d4 ro  single
initrd  /boot/initrd.img-2.6.28-11-generic

title  Ubuntu 9.04, memtest86+

kernel  /boot/memtest86+.bin
quiet

Now, you should have a successful triple-boot! Also, not you can restore your GRUB using each of their Live CDs (Restoring GRUB in Ubuntu).

This method can be used with any combination you like and number of OSes, but just limit to your hard drive capacity. Having multiple OSes is cool, but to much is just plain dumb. =)

Applications Menu Missing

Today, I was experimenting with my Ubuntu, when I noticed that my Applications menu in my panel had no contents, only Places and System. I did a little search and found a solution in the Ubuntu forums. To restore it back, issue the folllowing commands in the terminal.

rm /home/[yourUsername]/.config/menus/applications.menu

This will remove your current configuration, and reset a new config. After that, your Applications menu should be restored back to default.

Get Dropbox to Work on Jaunty Jackalope

I did a fresh install yesterday, and I got a problem on installing the latest Dropbox. The error was like this,

The program 'dropbox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadIDChoice (invalid resource ID chosen for this connection)'.
(Details: serial 734 error_code 14 request_code 53 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

To get it working, I did the following,
1. Install Dropbox's nautilus and daemon package

2. Download latest build of Dropbox (as of April 28, 2009), here

3. Issued the following command on the terminal

cd ~

rm -r .dropbox-dist/

tar -xzf dropbox-lnx.x86-0.6.510.tar.gz

4. Restart nautilus (I did a logout)

and voila! Dropbox is now working!

Adding JAVA_HOME in Ubuntu

I've been using linux (specifically Ubuntu) for quite some time now, I've been trying to migrate to linux from windows. One of the first thing I've encountered is adding an environment variable. Compared to windows, its very similar, only that you have multiple ways to do it. One way I find to be the easiest is by adding it to /etc/environment file. So here's how to do it.

1. Open /etc/environment as root in gedit (or any text editor you have)

sudo gedit /etc/environment

2. Add the following lines (remember to change the version to what you are also using).

JAVA_HOME="/usr/lib/jvm/java-1.5.0-sun"

3. Save it and log-off or restart you machine, that's it!

You can also add other variables like your MAVEN_HOME or anything you want.
