Update is not working due to Malformed entry error

Question

sudo apt-get update is not working, what should I do?

Answer 1

You are looking at a related file, but it's the wrong one. Your error clearly states that the problem is line one in the file /etc/apt/sources.list.d/dotnetdev.list which according to this should be deb [arch=amd64] http://apt-mo.trafficmanager.net/repos/dotnet/ trusty main for 14.04 and deb [arch=amd64] http://apt-mo.trafficmanager.net/repos/dotnet/ xenial main for 16.04. if the line you have exactly matches for your distribution you should report a bug. If not, fix it with your favorite editor.
