Hi,
I'm completely new to JIRA and just trying to get a version with a trial license running on my Linux machine (kubuntu). Installation process finished successfully, but when I try to start it in my browser it says "JIRA Startup Failed" and "The following plugins are required by JIRA, but have not been started: Atlassian Navigation Links Plugin (com.atlassian.plugins.atlassian-nav-links-plugin) Gadget Directory Plugin (com.atlassian.gadgets.directory) ....". How can I install these plugins?
