Hello everyone!
I recently changed my Operating system to Ubuntu 20.04 and tried to setup the machine for development.
I have open-jdk 8 installed,
openjdk version "1.8.0_292"
OpenJDK Runtime Environment (build 1.8.0_292-8u292-b10-0ubuntu1~20.04-b10)
OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)
on my machine and mysql 8.0.25
mysql Ver 8.0.25 for Linux on x86_64 (MySQL Community Server - GPL)
I have been following the wiki document, how to setup the OpenMRS Sdk. I have selected to run a Distribution having Reference application 2.12-SNAPSHOT
i have successfully installed the openmrs-sdk plugin and server on my machine but on running the command mvn openmrs-sdk:run -DserverId=server_name i get the following errors on the browser and console log .
HTTP Status 500 – Internal Server Error

I have read a thread where @kdaud talked something about mysql encrypting folder so a connection cannot be made 
Where might i have gone wrong. @sharif @mozzy @reagan @kdaud @herbert24 @dkayiwa @ibacher and anyone who uses Ubuntu.
Thanks
