I downloaded liferay-ce-portal-tomcat-7.0-ga6 from this link and tried to run the tomcat server with ./startup.sh and this is the following result :
newuser@my-Notebook:~/Downloads/liferay-ce-portal-tomcat-7.0-ga6-20180320170724974/liferay-ce-portal-7.0-ga6/tomcat-8.0.32/bin$ ./startup.sh

and in the log file, catalina.outit gives the error :

Error: Could not create the Java Virtual Machine.

I am using Ubuntu 18.04 LTS.
How to solve this issue ?
Be sure to have JDK 8 running the tomcat. Newest version is not yet supported.
Remove all the existing jdk's :
sudo apt-get purge openjdk*
The install java 8 :
sudo apt install openjdk-8-jdk openjdk-8-jre
