Whenever I try to install any package, I get the error "Unable to Download Packages", "Check your Internet connection". But the strange part is that I can use synaptic to download and install the same packages.

Any help would be great. Thanks.

Have you checked which server you are downloading from ? Try switching to main, i just recently had the same problem with the canadian server.

I had the same issue. It started after I switched from a wireless card to a standard ethernet connection. After I switched to ethernet, my internet browser (Chrome) and E-mail (Thunderbird) worked fine, but I was getting the same software update issues.

If you look in the upper right hand edge of the screen, there is a up-arrow/down-arrow symbol near the blutooth and speaker volume symbols. This is the network manager.

It you right-click on it with a mouse you should see a list of your wired and wireless connections. After I switched, Network Manager had a message at the top that said something to the effect of "Ethernet connection wired device not managed".

I found the article: network manager says "device not managed"

But to summarize, I used the following Command Line commands to make it work:

To do this - in a terminal:

sudo nano /etc/NetworkManager/NetworkManager.conf

Change the line 

managed=false

to

managed=true

Save (CTRLX, then Y and enter)

Stop and start network manager:

sudo service network-manager restart

And it should work (it worked for me).
