Can't startup webapp stuck in maintenance mode

I hope I have only to place the .war file in webapps folder of tomcat. I did so. I did with both java versions 7 and 8. Also with tomcat 7 and 8. Gives this error.

Did somebody tested this in the linux environment and got the same issue?

Additionally I gave chmod 777 opemrs.war and also did what was asked in the release notes.

What happens when you use this released version of the module? https://modules.openmrs.org/#/show/231/legacy-ui-module
