Cedega 7 install issue "cedega Error: Dependency is not satisfiable: python2.4-dbus"

Today i downloaded the .deb version of cedega from this URL http://www.cedega.com/downloads/

When i tried to install cedega i came across the following error:
cedega Error: Dependency is not satisfiable: python2.4-dbus


After some search i found out that in ubuntu 9.04 (Jaunty) the package python2.4-dbus was renamed to python-dbus. So this leads to a broken dependency error. The solution i found is:

Open a terminal and navigate to the directory you downloaded the .deb file from cedega. Usally this is your home folder or Desktop folder.
Execute the following commands by the order they appear:

$ mkdir -p cedega_000133_all/DEBIAN
$ ar p cedega_000133_all.deb data.tar.gz | tar zx -C cedega_000133_all/
$ ar p cedega_000133_all.deb control.tar.gz | tar zx -C
$ cedega_000133_all/DEBIAN/
$ mv cedega_000133_all.deb cedega_000133_all.prerebuild.deb

$ perl -pi -e 's/python2.4-dbus/python-dbus/' cedega_000133_all/DEBIAN/control

$ dpkg-deb --build cedega_000133_all
$ rm -rf cedega_000133_all
$ sudo dpkg -i cedega_000133_all.deb

Make sure you have write permissions to this folder if it is outside your home directory. If you don't have sufficient write permissions the build command will produce an error.
Hope this helps.

Mount iso file in Ubuntu

This post will show you 4 ways to mount an iso file like a normal cd/dvd drive in Ubuntu. By using these you don't have to write the iso file to a cd or dvd. They are ordered from the easiest to the hardest.



Mount iso using Gmount-iso.
This is a great program that i found recently. To install it just type:

sudo apt-get install gmountiso

The best thing with this program is that you can mount the image anywhere you want. You can even mount it on the cdrom folder. (if you execute it with sudo )

sudo Gmount-iso

Mount iso using nautilus.

This is the easiest and fastest way i know.

Step: 1
With this way you only have to install a .deb package. This package is called nautilus-mount-image and it can be found
http://launchpadlibrarian.net/18219053/nautilus-mount-image_0.2.0-1_all.deb
or
https://edge.launchpad.net/%7Ezootropo/+archive/+files/nautilus-mount-image_0.2.0-1_all.deb

After installing the package when you right click on an iso file you will see the option to Mount.
The only problem that i found with this way is that you cannot mount it where you want (in a folder of your choise) .


Mount iso using nautilus scripts.

To make this way work you need to create two nautilus scripts and put them in the correct folder.

Step:1
Create a new file named mount in the folder ~/.gnome2/nautilus-scripts. This file will mount the image file you want.

gedit .gnome2/nautilus-scripts/mount.sh

and copy the following and save the file

#!/bin/bash

gksudo -u root -k /bin/echo "got r00t?"

sudo mkdir /media/"$*"

if sudo mount -o loop -t iso9660 "$*" /media/"$*"
then
if zenity --question --title "ISO Mounter" --text "$* Successfully Mounted.

Open Volume?"
then
nautilus /media/"$*" --no-desktop
fi
exit 0
else
sudo rmdir /media/"$*"
zenity --error --title "ISO Mounter" --text "Cannot mount $*!"
exit 1
fi

Step:2
Create a new file named unmount in the folder ~/.gnome2/nautilus-scripts. This file will unmount the image file you previously mounted.

gedit .gnome2/nautilus-scripts/unmount.sh

and copy the following and save the file

#!/bin/bash

for I in "$*"
do
foo=`gksudo -u root -k -m "enter your password for root terminal
access" /bin/echo "got r00t?"`

sudo umount "$I" && zenity --info --text "Successfully unmounted /media/$I/" && sudo rmdir "/media/$I/"
done
done
exit0

and copy the following and save the file

#!/bin/bash

gksudo -u root -k /bin/echo "got r00t?"

sudo mkdir /media/"$*"

if sudo mount -o loop -t iso9660 "$*" /media/"$*"
then
if zenity --question --title "ISO Mounter" --text "$* Successfully Mounted.

Open Volume?"
then
nautilus /media/"$*" --no-desktop
fi
exit 0
else
sudo rmdir /media/"$*"
zenity --error --title "ISO Mounter" --text "Cannot mount $*!"
exit 1
fi

Step:3
Now we just have to give execution rights to the files we created.

sudo chmod +x .gnome2/nautilus-scripts/mount.sh
sudo chmod +x .gnome2/nautilus-scripts/unmount.sh

The only problem that i found with this way is that you cannot mount it where you want (in a folder of your choise) .

Using loop Kernel Module

This is the hardest way but the only one if you don't want to use a graphical interface.

Step:1
The first thing you need to do is create the directory that the iso is going to be mounted.

sudo mkdir /media/image_folder

Step:2
Now you have to load the loop mode to your kernel:

sudo modprobe loop

Step:3
Now we can mount the image file (image_file.iso) to the folder we created.

sudo mount image_file.iso /media/image_folder/ -t iso9660 -o loop

Step:4
When we want to unmount the image file

sudo umount /media/image_folder/

Disable Xgl server

This post will show you how to disable xgl server in Ubuntu. With this way it is no longer necessary to use any special X session to disable xgl server. I used this way because my laptop has an ati graphics card (Mobility Radeon X1700) and i had many problems with xgl server.

Step 1:
The only thing you need to do is create an empty file named disable in your home directory in the path ~/.config/xserver-xgl/

cd .config/xserver-xgl/

If the above path does not exist create it

mkdir .config/xserver-xgl/

Step 2:
Now to create an empty file named disable:

>disable

Now you just have to logout and when you login xgl server won't start.

Create an iso file from a cd,dvd or folder

This post will show you how to create an iso file from a cd, dvd or a folder.

Create .iso from CD - DVD


Step 1:
Now we move to the creation of the .iso file. The following command will create the iso file named test.iso.

dd if=/dev/cdrom of=test.iso bs=1024

Now wait for the command to finish. This may take some time depending on the size of the data on the disc.


Create .iso from a folder

Step 1:
In order to create an iso from a folder we need to install the program mkisofs. Just type:

sudo apt-get install mkisofs

Step 2:
Now we create the iso file (test.iso) from a folder in our system.

mkisofs -r -o test.iso /path_to_folder/

Step 3:
It is suggested to create an MD5 checksum from the iso file so we can validate the integrity of the file in the future. This is done with the following command:

md5sum test.iso > test.iso.md5

Open desktop environment througth ssh

This post will show you a very simple way to open a desktop environment such as gnome, kde or xfce through ssh. This way has been tested on Ubuntu and Kubuntu.



Step 1:
You need to install open ssh client and server

sudo apt-get install openssh-client openssh-server

Step 2:
On the client machine you need to open a new screen. In order to do this press Ctrl+Alt F2 (or any f2-f6) and login.

Step 3:
When you are logged in run following command to open a new X Session in screen 1 (you can open it in other screens ex. 2. If you want to go to another screen press Ctrl+Alt f8 - f12)

xinit /usr/bin/xterm -- :1

When the session is opened you will only see a terminal.

Step 4:
On that terminal you will execute this command to open an ssh connection.

ssh -X username@host_ip

or

ssh -Y username@host_ip

The difference between the above commands is that the first one is subjected to X11 SECURITY extension restrictions by default. The second is not. So it is advised to use it with caution.

Now you have to enter your password (from your account on the server) in order to login.

Step 5:
When you are logged in the remote computer according to the X environment it has installed you have to enter the following to run it.

For machines with Ubuntu usaly:

gnome-session

or if you have KDE installed type :

startkde

For machines that have XFCE installed type:

startxfce4
