How can i tell meego that remember that when someone uninstall restore those files previous state?
Debian packaging allows you to have a file that is executed in the uninstallation. Put it in the debian folder and name it as postrm

here is an advanced example of something I'm using (it will execute different options depending on what the user asked, i.e. upgrade, remove or purge):

Code:
#!/bin/sh
echo "BEGIN postremove"

case "$1" in
upgrade*)
    echo Leaving files for use by upgrading version. 1>&2
    ;;
remove*)
    rm -f /etc/sudoers.d/cleven.sudoers
    update-sudoers
    ;;
purge*)
    rm -rf /opt/cleven
    rm -rf /home/user/.cleven
    update-sudoers
    ;;
esac
echo "  END of postremove"

Thank you Saturn but that is pure chinese for me

I saw in some deb packages something like this, for ex.:
theme.ini and below theme.ini.backup (or something like that, this is not exactly).

I assume that the files with the .backup extension will be restored after uninstallation.

Does anyone know something like this? It is possible?

I think that this method should make a backup of each file that would be replaced/edit/deleted with a .backup extension

your prerm file can contain the commands for replacing back the original files...

How would be a prerm script to replace "/usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style/libsysuid-screenlock-nokia.css" to libsysuid-screenlock-nokia.css.backup

And then a postrm script to restore that .backup file?

If could someone post an example so i can get a better idea

@flotron replace also #!/bin/bash with #!/bin/sh
because bash is not by default installed, but sh is.

For sure use sh instead of bash.

And I assume, that 'exit 0' will exit the installation, not only this script. Just remove that.
And there should be no need for a blank line at the end, but it does not hurt also.

I change bash to sb and remove exit 0 and still get "install interrupted" try again?

Maybe i need some permission to modify that file?
"/usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style/libsysuid-screenlock-nokia.css"
