Hi,
Reinstallation of Ubuntu without the loss of data
If in case the Ubuntu installed in the computer has been corrupted because of the changes we made in the libraries and we don't want to lose the data, we need to upgrade to the later versions of the ubuntu as suggested here:
1. https://help.ubuntu.com/community/UbuntuReinstallation
2. http://superuser.com/questions/923926/r ... osing-data


Yours Sincerely,

restoration of removed unity desktop
This is a subjective description of how i got my unity desktop restored.
1. I was doing some changes in the ubuntu software package manager and this caused the unity desktop removed in my Ubuntu 14.04 computer.
2. Unable to find relevant solution tools, i decided to upgrade the computer system to Ubuntu 16.04 via USB installation.
3. In Ubuntu 16.04, similar to the previously installed Ubuntu 14.04; Unity desktop could not be stored.
4. In order to use desktop shell, i utilized the gnome-shell feature. Thanks to gnome-shell feature that has helped me persevere and keep going with Ubuntu.
5. Then, during a lot of hit and trial, this actions restored Unity desktop in 16.04 (also can be applied to/in Ubuntu 14.04)
Problem when doing regular update now via gnome-shell:
Code: Select all
$ sudo apt-get update

Code: Select all
...
AppStream cache update completed, but some metadata was ignored due to errors.


Now, the solution starts from this reference link:
A. Problem Identification
1.http://askubuntu.com/questions/854168/how-i-can-fix-appstream-cache-update-completed-but-some-metadata-was-ignored-d
This reference hints to the solution outlined in step B.

B. Solution is "Enable the backports repository via Softwares and Updates"
1.http://askubuntu.com/questions/25717/how-do-i-enable-the-backports-repository

So, going in-accordance to the methodology outlined in step B (enabling the backport repository) , i could get the temporarily-lost Unity desktop , recovered or restored back in the Ubuntu computer.
Now, i have learned features of gnome-shell and can use both of gnome-shell and unity-desktop in Ubuntu 16.04.

Yours Sincerely,
Anil Kunwar
