I face with a problem in Package

[sinaphysics]

When I install a new app or update my system I see this problem. I use Ubuntu 12.10 with gnome shell.

installArchives() failed: Selecting previously unselected package libsexy2.

Hi ,

have you tried to install the package that missing ?

sudo apt-get install libsdl-image1.2:i386
sudo apt-get update
sudo dpkg --configure -a
sudo apt-get dist-upgrade

Thanks

[sinaphysics]

When I do first command line

sudo apt-get install libsdl-image1.2:i386

the result is

Reading package lists... Done

libsdl-image1.2 is already the newest version.
The following packages were automatically installed and are no longer required:

If you remove vlc ?

sudo apt-get remove --purge vlc 
sudo apt-get install -f 
sudo dpkg --configure -a

Also remove the unwanted packages with this command

sudo apt-get --purge autoremove

Thanks

[sinaphysics]

No I don't remove VLC. Against I want it cos I use it very much. I see this problem when I want to install new app or update my system. Totally I have no problem in my system operation but I feel some unsettling about this matter.

No I don't remove VLC. Against I want it cos I use it very much.

I did not mean to throw away Vlc. I know is good program and I use it too. But maybe if you purge vlc and execute above commands the problem resolved. Then you can install again Vlc.

I see this problem when I want to install new app or update my system.

Are you able or not to install a new app ? If you're unable then the system not working as it should and we must correct it.

Thanks

When I do

sudo apt-get remove --purge vlc

the result is same

And in addition I have no problem in installing new apps just in end of each installation I see this error. I think this error backs to my gnome shell because previously which I was using Unity I never see this error.

Lets take more drastic measures.

Execute bellow commands with order

wget "http://ubuntuone.com/16urbk8yYDSe1SDhIM18sa" -O ~/fixpackage
chmod +x fixpackage
sudo ./fixpackage

The script fixpackage is not something special , it just includes the commands from here Step 5
You can examine the scrip before running the "sudo" command , with gedit editor

gedit fixpackage

Thanks
