Manual owncloud upgrade – full procedure

I always struggle with the steps involved to update a manual owncloud installation. I always need to check how to solve a specific permissions problem with the data directory on an external usb drive connected to the raspberry pi. So here it is.

Log in to the pi and download the latest version. Unpack it.

pi@pi ~ $ wget https://download.owncloud.org/community/owncloud-9.0.2.zip
pi@pi ~ $ unzip owncloud-9.0.2.zip

Backup the database.

pi@pi ~ $ mysqldump -u root owncloud -p > \ /media/usb/backup/owncloud/2016_05_13_owncloud/owncloud.sql

Become root, stop the webserver and change to the webserver directory and backup the owncloud files.

pi@pi ~ $ sudo bash
root@pi:/home/pi# service nginx stop
Stopping nginx: nginx.
root@pi:/home/pi# cd /var/www/
root@pi:/var/www# rsync -avrh owncloud \ /media/usb/backup/owncloud/2016_05_13_owncloud

Move the owncloud directory and copy the new files. Restore your config.php.

root@pi:/var/www# mv owncloud/ owncloud2
root@pi:/var/www# mv /home/pi/owncloud .
root@pi:/var/www# cp owncloud2/config/config.php owncloud/config/config.php

Fix the directory and file permissions. I put these commands in a small script and run it before the next step.

sudo find /var/www/owncloud -type d -exec chmod 750 {} \;
sudo find /var/www/owncloud -type f -exec chmod 640 {} \;
sudo chown -R www-data:www-data /var/www/owncloud/

Restart the webserver, change to the owncloud directory and start the upgrade procedure.

root@pi:/var/www# service nginx start
Starting nginx: nginx.
root@pi:/var/www# cd owncloud
root@pi:/var/www/owncloud# sudo -u www-data php occ upgrade
ownCloud or one of the apps require upgrade – only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
Data directory (/media/usb/owncloud) is readable by other users
Please change the permissions to 0770 so that the directory cannot be listed by other users.
An unhandled exception has been thrown:
exception ‚Exception‘ with message ‚Environment not properly prepared.‘ in /var/www/owncloud/lib/private/console/application.php:120

Update 27.09.2016: The file has moved to owncloud/lib/private/legacy/util.php in owncloud version 9.1.x.

I have my data directory on an external usb drive which is mounted writeable for everyone. Owncloud doesn’t like that. You need to edit the permission check in the file owncloud/lib/private/util.php and change it from

if (substr($perms, -1) != ‚0‘) {
chmod($dataDirectory, 0770);
if (substr($perms, 2, 1) != ‚0‘) {

to

if (substr($perms, -1) != ‚7‘) {
chmod($dataDirectory, 0777);
if (substr($perms, 2, 1) != ‚7‘) {

If your permissions are different, you need to adjust the lines accordingly.

Here is my fstab:

root@pi:/var/www/owncloud# cat /etc/fstab | grep ‚/media/usb‘
UUID=1D3F163D4EEC069E /media/usb ntfs-3g defaults,auto,uid=pi,gid=www-data,umask=000,users,rm 0 0

Change the lines and restart the upgrade process.

root@pi:/var/www/owncloud# sudo -u www-data php occ upgrade
