DietPi-Software | ownCloud/Nextcloud: Fix/Polish Phase II

[MichaIng]

• Enable maintenance mode before reinstallation via patchfile to suppress error caused by stopped MySQL.
• Suppress Apache2 messaged about already enabled modules and sites.
• Suppress occ maintenance:install error message, if instance is already installed.
• Fixed typo about ncc command.
• Intelligent handling of maintenance mode during dietpi-services.
• Main folders should be removed after mysql user dropping, otherwise we can't find user names.
• Correctly "add" cronjob, instead of overwrite.

Just realized, that bashrc aliases are not present inside scripts. Therefore we would need binaries:
nano /usr/local/bin/occ

#!/bin/bash
sudo -u www-data php /var/www/owncloud/occ $*

Does work as expected.

Or we just use the full command inside our scripts?

Personally I would go with the binaries, because it is also most easy and safe to just handle files instead of conditionally adjust their content 😄. But in the end it is absolutely not important if and how.

Testing:

• Reinstallation/dietpi-update works fine now without unnecessary warnings and existing installation stay untouched, just selective secure enhancements are done, if not yet applied by user.
• Uninstallation
• Fresh installation
