XMC Ubuntu upgrade - FW policy

[Ronald_Dvorak]

I've some troubles to upgrade my XMC because of the required Ubuntu update - looks like the customers firewall needs some settings changed to allow access to the outside resources.

Is there a port/IP/website list that is required to allow the Ubuntu upgrade.

Thanks,
Ron

Reading that you should be able to edit

code:

/etc/apt/sources.list

and select one of the Ubuntu mirrors and just unfirewall that host.
