Oh that's just your locale settings. Sometimes goes by "language settings."
I work primarily with xubuntu so your experience may be slightly different. But you know how after you first install, it starts griping that your language settings need to be updated? You have to take care of that right away.
So the first task is to get your network settings right so you can connect to the internet, then deal with the language gripe right away. iirc you have to update/install twice before ubuntu is happy.
How to fix it after the fact (like if you dismiss the warning without dealing with it) is not well documented. You can try settings - language support and see if it gives you the opportunity to update. Search the ubuntu forums, just copy/paste the error message, or search under locale or language settings. Or, reinstall and deal with the language issue. Not quite time yet to show ubuntu who's boss; that comes later. You'll see. For now just do what it says.
Fix the locale issue and then turn off upgrades, the most aggravating thing about plain-vanilla Ubuntu, other than that ridiculous Unity desktop, is that it'll sneak in major upgrades (like from 16.04 to 16.10) that may not work with your hardware and drivers. Depends. Things are very fluid right now. Just get amdgpu-pro installed; if you can get it to "take," things get easier from there.
I installed the amdgpu-pro 16.40 successfuly now there is a new problem
... The miner reads the card with low memory and comput units and also says "amd ADL not found " so i am stuck on this ...also tried to reinstall the drivers many times with the same problem.
