It is wiered that I'm not able to reinstall unity-2d on my system.

I removed it as it was not ready to go into the 2D mode. I have XRDP install for which I need Unity-2D.

after removing the unity-2d as it was not working properly. I run below command and then rebooted system before trying to reinstall it.

apt-get -f purge unity-2d lightdm
add-apt-repository --remove ppa:unity-2d-team/unity-2d-daily
apt-get -f purge
apt-get -f remove
apt-get -f autoremove
apt-get -f remove
apt-get clean
apt-get autoclean
dpkg --configure -a
then rebooted the system using init 6

now I took the ssh of my system and then i reinstalled unity using below commands

apt-get -f install --reinstall lightdm
root@searce-OptiPlex-380-01:~# add-apt-repository "deb http://ppa.launchpad.net/unity-2d-team/unity-2d-daily/ubuntu trusty main"
root@searce-OptiPlex-380-01:~# add-apt-repository "deb-src http://ppa.launchpad.net/unity-2d-team/unity-2d-daily/ubuntu trusty main"
Error: 'deb-src http://ppa.launchpad.net/unity-2d-team/unity-2d-daily/ubuntu trusty main' invalid
root@searce-OptiPlex-380-01:~# add-apt-repository ppa:unity-2d-team/unity-2d-daily

To install Unity 2D, type the following commands in a terminal:

$ sudo add-apt-repository ppa:unity-2d-team/unity-2d-daily
$ sudo apt-get update
$ sudo apt-get install unity-2d

This will install all of the necessary dependencies to run Unity 2D, including a "Unity 2D" session that you'll need to login with.

Then do the following:  * log out  * log back in and choose the "Unity 2D" session in the drop-down menu at the bottom of the login screen  * you will then be running Unity 2D

OK

then when I ran apt-get update everything goes well except 2 things below:

1) Hit http://archive.ubuntu.com trusty-backports/main Sources Err http://ppa.launchpad.net trusty/main amd64 Packages 404 Not Found Hit http://archive.ubuntu.com trusty-backports/restricted Sources Hit http://archive.ubuntu.com trusty-backports/universe Sources Err http://ppa.launchpad.net trusty/main i386 Packages 404 Not Found

2)

E: Some index files failed to download. They have been ignored, or old ones used instead. root@searce-OptiPlex-380-01:~#

above errors stared coming after I imported the PPA file of unity-2d, before that it was not there, still tried to reinstall unity-2d using below commands:

root@searce-OptiPlex-380-01:~# apt-get -f reinstall unity-2d
E: Command line option 'f' [from -f] is not known.
root@searce-OptiPlex-380-01:~# apt-get -f install unity-2d

root@searce-OptiPlex-380-01:~# restart lightdm
lightdm start/running, process 2926
root@searce-OptiPlex-380-01:~# 

didn't see any error while installing but even after restarting the lightdm or even after rebooting the system I am not able to see the unity-2d option at the login screen nor it is working in XRDP. Also I do not see any menu or Icons when I login to the system physically or over XRDP.

can anyone help me. Thanks in advance.
