It keeps showing Error with “failed to start light Display Manager” . i update the System from 16.04 to 18.04 , and this Problem appears. Anyone gets same Problem and please help me!

Hi,

What was your method to do the update? If you update system from 16.04 to 18.04, do you mean you upgrade from rel-28 to rel-32?

I guess the method you tried may not correct, becasue rel-32 does not use light DM anymore.

And if you are new to this device, here is the download center with many document link.
If you have no idea what is rel-28 and rel-32, maybe you could read the document first.
