[arch-general] Nextcloud installation problems

[Peter Nabbefeld]

Hello,

I've got a problem trying to install nextcloud (I just want to try it 
out, so I don't have any knowledge about it, yet):

Nextcloud is not installed - only a limited number of commands are available
No database drivers (sqlite, mysql, or postgresql) installed.


Cannot write into "apps" directory
This can usually be fixed by giving the webserver write access to the 
apps directory or disabling the appstore in the config file. See 
https://docs.nextcloud.com/server/12/go.php?to=admin-dir_permissions

PHP module GD not installed.
Please ask your server administrator to install the module.

An unhandled exception has been thrown:

As one of the messages is "PHP module GD not installed. Please ask your 
server administrator to install the module." it's propably not depending 
on a needed module?

Kind regards
