setup is: 410C with Ubuntu - Release 15.06 - connected to network via WIFI.
When I do sudo apt-get update it starts to run as normal, but always ends with several "duplicate sources" warnings, then says "you may want to run apt-get update to correct these problems"
Ok so I run it again - same thing.
Are others seeing this? It doesn't give you a comfortable feeling that things are right with the repos and packages. I wonder if this causes any problems or is it ok to ignore?
