SOLVED - Upgrade to 10.0.9 results in owncloud not found error 404

Hello,
Today I upgrade my personal owncloud server to 10.0.9. The upgrade seemed to have worked at first as I could login and saw the owncloud X logo. It all seemed to work. As I also did some other upgrade and ran autoremove.
After that I could no longer login into and got Error 404. /owncloud/index.php/login was not found on this server.
I did some search but I am not an expert…

SOLVED - Issue came from owncloud.conf file which was empty at /etc/apache2/conf-enabled/owncloud.conf cp it from /etc/apache2/conf-available/owncloud.conf solved the issue.
