Migration Ubuntu to Kubuntu

Already install ubuntu and want to migrate to kubuntu?

This can be solve!

In ubuntu, type command:

apt-get install kubuntu-desktop.

Then boot up and logout/login menu, click option and you will see words “session” before you enter username and password.

In another words you can apply either Ubuntu(GNOME) or Kubuntu(KDE) by switching the session. Sound Interesting?yess~~

Another method:

I HAVEN’T tried this method below but you can try it.

*Notes: I got this from internet.

To prevent KDE apps from showing up in Gnome menus and vice-versa, do the following before you install kubuntu-desktop :

(you can also create a small cleaner.sh script witht he following and run it as root)
$ sudo -s -H
#cd /usr/share/applications
#for i in *.desktop; do \
# if ! grep -q ^OnlyShowIn= $i; then \
# echo ‘OnlyShowIn=GNOME;’ >> $i \
# fi
#done

Now, after installing kubuntu-desktop do:

$cd /usr/share/applications/kde
$sudo -s -H
#for i in *.desktop; do
# if ! grep -q ^OnlyShowIn= $i; then
# echo ‘OnlyShowIn=KDE;’ >> $i
# fi
#done

What we did above was to tell the Gnome apps to only show in the gnome menus, and later, the KDE apps to only show in KDE menus.

Thank You

Unable to get exclusive lock

Showing display:

This message is telling you that there is a lock file preventing your package manager from getting exclusive access. It occurs when your power goes out, etc, before they are completed, the lock file remains and the next manager believes another manager is already running.

So it’s probably that some update process happening behind, somthing that’s unfinished.

Try the following command:

apt-get clean

apt-get -f update

It will clear the cache and terminate any unfinished business and restart again.

If still getting same error, use command:

ps -ax

It will show list of current running process.

To terminate running process use command:

sudo kill <process number>

Hopefully this method will work.Gudluck!
