Unable to create and add files and folders

[skjnldsv]

Hey!

Any errors in your nextcloud.log ?
When you say upload, for the guest, you mean via web? Or via a client?

[kabia06]

Hello,

Thank you for your feedback @skjnldsv .

Yes, in the Nextcloud.log file I have some information. What I mean is that when I try to create a folder or upload a file, nothing appears in this log file. However, when I try to create a text file, I do have logs that appear. Here are the logs in question:
{"reqId":"1iJDYtUvBK1tyjJbUq92","level":3,"time":"2024-03-01T08:37:02+00:00","remoteAddr":"MY_IP_ADDRESS»user":"[email protected]","app":"no app in context","method":"POST","url":"/ocs/v2.php/apps/files/api/v1/templates/create","message":"No create permission for path \"Nouveau fichier texte.md\"","userAgent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:122.0) Gecko/20100101 Firefox/122.0","version":"28.0.2.5","exception":{"Exception":"OCP\\Files\\NotPermittedException","Message":"No create permission for path \"Nouveau fichier texte.md\"","Code":0,"Trace":[{"file":"/var/www/nextcloud/lib/private/Files/Template/TemplateManager.php","line":162,"function":"newFile","class":"OC\\Files\\Node\\Folder","type":"->"},{"file":"/var/www/nextcloud/apps/files/lib/Controller/TemplateController.php","line":80,"function":"createFromTemplate","class":"OC\\Files\\Template\\TemplateManager","type":"->","args":["*** sensitive parameters replaced ***"]},{"file":"/var/www/nextcloud/lib/private/AppFramework/Http/Dispatcher.php","line":230,"function":"create","class":"OCA\\Files\\Controller\\TemplateController","type":"->","args":["*** sensitive parameters replaced ***"]},{"file":"/var/www/nextcloud/lib/private/AppFramework/Http/Dispatcher.php","line":137,"function":"executeController","class":"OC\\AppFramework\\Http\\Dispatcher","type":"->"},{"file":"/var/www/nextcloud/lib/private/AppFramework/App.php","line":184,"function":"dispatch","class":"OC\\AppFramework\\Http\\Dispatcher","type":"->"},{"file":"/var/www/nextcloud/lib/private/Route/Router.php","line":315,"function":"main","class":"OC\\AppFramework\\App","type":"::"},{"file":"/var/www/nextcloud/ocs/v1.php","line":65,"function":"match","class":"OC\\Route\\Router","type":"->"},{"file":"/var/www/nextcloud/ocs/v2.php","line":23,"args":["/var/www/nextcloud/ocs/v1.php"],"function":"require_once"}],"File":"/var/www/nextcloud/lib/private/Files/Node/Folder.php","Line":199,"message":"No create permission for path \"Nouveau fichier texte.md\"","exception":{},"CustomMessage":"No create permission for path \"Nouveau fichier texte.md\""}}

When I say file upload, I mean file upload via web interface. The tests are carried out via the web interface. I've never run the tests via the client.

For your information, the tests are performed from different browsers (Firefox and Google Chrome). Furthermore, the logs I provided in my initial message are logs that appear in the file /var/log/apache2/nextcloud.access
Also, here's my Nextcloud version:

sudo -u www-data php occ -V
Nextcloud 28.0.2

Version of Guests plugin:
guests: 3.0.1

Thank you.

What quota has your guest user?

[kabia06]

When I create a user with Guests there is no default quota, it doesn't seem to be taken into account. I change it manually to 10GB.

[skjnldsv]

Can you do an occ user:info your-guest-userid ? :)

[skjnldsv]

I just tested it, and it works fine, if I change the quota of the quest to something specific, it works.
Can you upgrade to latest 28.0.3 please? :)

[kabia06]

I am reaching out to inform you that, despite updating our Nextcloud server to version 28.0.3, the issue faced by Guest users persists. These users are still unable to create content (files, folders) or upload files to the server.

Disturbingly, the majority of these actions do not generate any error messages in the logs accessible through the Nextcloud web interface. However, an exception occurs when attempting to create text files, where we receive the following error: NotPermittedException No create permission for path "Nouveau fichier texte.md".

I have double-checked the settings of the Guest plugin, ensuring that all necessary applications were enabled for Guest accounts, but, unfortunately, this has not resolved the issue.

For reference, here are the details of the concerned Guest user account:

sudo -u www-data php occ user:info [email protected]
- user_id: [email protected]
- display_name: KABIA TEST
- email: [email protected]
- cloud_id: [email protected]@my-nextcloud.fr
- enabled: true
- groups:
  - guest_app
- quota: 10 GB
- storage:
  - free: 10737418240
  - used: 0
  - total: 10737418240
  - relative: 0
  - quota: 10737418240
- last_seen: 2024-03-01T08:36:25+00:00
- user_directory: /data/nextcloud-data/[email protected]
- backend: Guests

I appreciate your prompt attention and support in resolving this issue. Should you require any additional information or specific logs to diagnose this problem, please do not hesitate to ask.

Thank you in advance for your help.

Best regards,

I will need a screenshot of your network requests.
Before you do anything, still on the development tools, there is a tab called network. Click on it and then the xhr filter. Do your action and screenshot the network log like this:

Hello,

I'm sharing the observations you requested. I tried to perform the same actions discussed on the Guest account. Here are the three actions I undertook in order:

1. Creation of a text file
2. Creation of a folder
3. Upload of a file

At each step, I received a 403 response for my requests. This indicates that access was denied for these specific actions on the Guest account.

Thank you in advance for your feedback and assistance!

Best regards,

[skjnldsv]

Can you post the content of the first 403? (or all of them) ?
Click on it, and you'll see the response tab

[kabia06]

Here are the results of the various queries in the following order:

• Folder creation
• File creation
• Upload a file (an image)

New folder :

<?xml version="1.0" encoding="utf-8"?>
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
  <s:exception>Sabre\DAV\Exception\Forbidden</s:exception>
  <s:message/>
</d:error>

New document :

{
	"ocs": {
		"meta": {
			"status": "failure",
			"statuscode": 403,
			"message": "Impossible de créer le fichier à partir du modèle"
		},
		"data": []
	}
}

Upload file :

<?xml version="1.0" encoding="utf-8"?>
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
  <s:exception>Sabre\DAV\Exception\Forbidden</s:exception>
  <s:message/>
</d:error>

Can confirm that this is an issue in NC28.
