I initially scp atlassian-servicedesk-3.15.3-x64.bin from the site to my home directory on my linux server. I ran the installer following the prompts for the upgrade. Once completed i was unable to either access the site or once i did log in it was white blank screen. I went ahead an uninstall service desk and now unable to create the directory once running the installed again.
error:
The directory you have selected is not a valid JIRA service Desk installation directory.
