So, you have no connection? Ping a host.
Make sure that's it's your internet connection first. I'm having a difficult time understanding the actual problem without seeing what the output of you commands are.

Hi:

From what you are describing it sounds like the DE and the GUI are gone. And other things are badly misconfigured.

***A fresh installation is most likely the 'best way to go'.***

-:::-As long as I have been here I've seen many folks have issues with upgrading from one version to another with any of the *buntu versions.-:::-

Xubuntu 14.04 became unstable for me a while back. A fresh installation of Xubuntu 16.04 has been a complete success.

Ok. If you know your interface name, i.e eth0 or wlan0, then try to manually bring it up with:
If you don't know your interface name, then use:
To find out.

I feel like I am wandering off topic, because the initial post said that you had a blank screen, yet you are still able to attempt installing packages. So the issue is that your DE isn't starting up? Or am I misinterpreting the issue?

Yeah bLank screen like this

And This is result of lspci cammand

Any solution guys

First, it sounds like you have more than one problem, one of which is not a blank screen but your Desktop Environment not starting on boot. Secondly, you have no connectivity which I assume you had before you upgraded. You posted some screenshots which show you typing in the commands which I have suggested to no avail.

Perhaps, you could:
1. Let us know how you have attempted to troubleshoot the issue.
2. Let us know if all of your original files and data is still intact post-update
3. Are there any additional error messages or do you just have no connectivity and no GUI

I don't use any of the Debian nor Ubuntu derivatives and therefore am not too familiar with the entire install process. More information would definitely be appreciated. Perhaps someone that is more familiar with lubuntu could offer a lifeline.

Ztcoracat raises a great issue. An upgrade from 14.04 to 16.04 is just too many to have it work well. The best way to move from one LTS release to the next is to save your data and reinstall. It is just cleaner and easier in the long run.

If you think a bit you will realize there was 14.10, 15.04 and 15.10 in between; just too many changes.

I think your best solution is to look at a reinstall. Do you have a separate /home partition?

Thanks jkirchner-:)

To many things go wrong with upgrades I've seen it many times on my Linux machines and on a handful of our members machines here at LQ.

-::::-A fresh installation is most practical.-::::-

OP is in tty mode only. This suggest's that the DE and the GUI are gone.
Startx fails to load:-

Most likely hosed by the upgrade.

1. Let us know how you have attempted to troubleshoot the issue.
I tried to update and upgrade using apt-get update and upgrade
and nothing solve my problem
2. Let us know if all of your original files and data is still intact post-update
my personal files are there still there nothing
The other files from previous release idont know
3. Are there any additional error messages or do you just have no connectivity and no GUI
just those two

Running the update and upgrade cmd will not correct a DE and the GUI that got hosed by an upgrade that left the system badly misconfigured/hosed.

The best thing that you can do at this point seriously; is use a Live Linux CD and retreive your files and copy them to a usb flash drive or an external HDD.

And, perform a fresh installation of Lubuntu 16.04.

#!/bin/bash

I'd be "very surpised" if a Live Linux CD in 'Rescue Mode' would work.

Upgrading from LTS releases such as 14.04 to another LTS release are direct and don't include any interim release upgrades. Going from 14.10 to 16.04 would require going first to 15.04 then 15.10 and finally 16.04. I did an upgrade from 12.04 to 14.04 which took over 3 hours while a new install took < 30 minutes so a new install in your case after backing up will be simpler. Ubuntu link on upgrades below.

I notice something i looked for the resolv.conf file its empty i tried to do
Sudo nano /etc/resolv.conf and it gave me a new file its like resolv.conf empty or what
https://ibb.co/mHWBtv

BTW itts works the only thing its got to my way in the end to connect to the internet is that there is no resolv.conf file

Glad to hear it works.

Here's some information on the resolv configuration file.
