Hi,

change your software sources download location per the update guide and try again:

Hi Wolfman. Is it possible that you can provide more clear instructions possibly with screenshots? This is a major issue for newbies and the only real problem I see with Zorin OS for newbies. It would be greatly appreciated.

Hi I cant do screenshots at moment as not got a working Zorin due to issues with this PC!

1. Go to Menu | System Tools | Administration | Software Updater and launch it.

2. After it has updated itself, click on the 'Settings' button.

3. Click on the left-most tab and you should see the server that you are pointing to in your location of the world - use the drop-down arrow at the side of it and select 'Main Server'.

Check out my Zorin updates and tweaks video here: https://vimeo.com/135585793
Hope this helps!

Hi,

open System Settings > System > Software & Updates and make sure you have "Download from" set to "Main server", let it reload and try updating again using either synaptic or Software Updater from the System Tools menu:
