Impossible to create a folder or a file with a special character in its name

gbprod · September 8, 2018, 4:07pm

Nextcloud version : 13.0.5
Operating system and version : debian stretch
Installed using Snap

I’ve freshly installed nextcloud on a clean debian stretch server using snap and it seems impossible to create a folder or a file with special characters. I’m using an OpenStack storage with External Storage plugin.

Steps to replicate it:

Install nextcloud on debian stretch using snap and configure a folder on Openstack Storage (eg. OVH Object Storage)
go to “Files”
Create a new folder named “tété”
An error appear : Could not create folder “tété”

The output of your Nextcloud log in Admin > Logging:

Can you create files/folders on local storage with special characters (to verify your configuration)?
Can you directly access the object storage (without Nextcloud) and try to create such a folder (to check the external storage compatibility for special characters)?

I can create folder with special characters on local storage
If I create folders on Object Storage without nextcloud then appear on the storage but they are invisible on Nextcloud

Seems that there is a communication problem (Guzzle) between Nextcloud and Open Storage.

Seems that the normalizePath method in the /apps/files_external/lib/Lib/Storage/Swift.php file has a bug. maybe we should add a urldecode here ? (I can’t test it now…)

In this case it would be the best to share this information with the developers in a bug report on github.com/nextcloud/server/issues

Ok, Thanks

For reference there are two issues for this problem, one closed with no action taken (https://github.com/nextcloud/server/issues/4036) and one still open (https://github.com/nextcloud/server/issues/15849).
