Error when I use bin file upgrade: 'Could not create this file. Shall I try again?'

[fanxiao01]

When I upgrade with the bin file, I go to the extract file and say “/usr/local/confluence/current/jre/./._bin 、Could not create this file. Shall I try again?”. I look in the directory and there is no jre directory

This question was posted a while ago but since there are no answers to it and I just had the same issue, I'll share my experience here.

In my case, the problem was the installation directory was /opt/atlassian/confluence_vernum and then we had a symbolic link for confluence -> confluence_vernum. As part of the upgrade, the installer backs up the installation dir into a ZIP file and deletes the directory, then it creates it again (probably unzipping) the new version's files.

When the installer stopped with that message "Rolling back changes", I checked the filesystem and saw that I was left with a symbolic link (still existing) pointing to a folder that didn't exist anymore. I therefore deleted the symlink, unzipped the backup that had been taken by the installer and renamed the folder to plain "confluence". I then run the installer once more and the installation finished successfully.
