I believe the error is to do with localtime file getting overwritten in run.sh script.
i get this error when i run
docker start -a owncloud
Setting timezone to UTC… ln: cannot remove ‘/etc/localtime’: Device or resource busy
you can check and see, I bypass it by editing the run.sh so as not to create a link to that file
ln -sf “/usr/share/zoneinfo/$1” /etc/localtime
to
ln -sf “/usr/share/zoneinfo/$1” /etc/localtime2
Restart the RockOn and It will work
am sure the time will be wrong now, but at least I can test the owncloud.
