We got the same error on upgrade. Try going to the path and see if it exists

The problem is, symlink for confluence.

Just try this:

Check if the confluence directory (with a symlink is there or not)
$ ll /opt/atlassian

if you cant find confluence directory, create one with the 

or

if you are not able lo go inside the directory, then it must be issue with symlink
$ cd /opt/atlassian/confluence/jre

How to create a new/valid symlink to confluence directory
ln -s confluence atlassian-confluence-6.15.8

Hi @Graeme Donald ,

Please check permission on the server. User that run Confluence should have full read/write permission to all directories (especially Home directory).

[Graeme Donald]

Confluence Home directory (/var/atlassian/application-data/confluence) is rwxrwxrwx & owner is Confluence, Group is Confluence, and user is a member of the Confluence group.
