Frankly, I don't know if this is a problem with "server" or "desktop", but the overall effect/interaction is causing problems

Steps to reproduce

  1. Install NC18.
  2. In the web-interface navigate to a directory, click into the workspace area at the top. This causes NC server to create a Readme.md file (regardless of content).
  3. Have a windows client syncing that folder.

Expected behaviour

A single readme.md file (in whatever case) is created, whether empty or with some content.

Actual behaviour

Three files with varying-case filenames are created.

image

Windows' based desktop clients repeatedly error. This results in a locked client, so files are not being synced.

Server configuration

Operating system: ubuntu 14.04 and 16.04

Related: https://help.nextcloud.com/t/attention-posible-case-sensitivity-clash/5345/3

From that, I don't disagree that the server is not responsible for case-handling on the client, so that is certainly an issue for https://github.com/nextcloud/desktop. However, why are three files created? The fact that three files exist suggest the server had something to do with it, otherwise there would be only one.

I've cross-posted an issue as nextcloud/desktop#1755, which I think is more likely the cause. The logs there are more recent and detailed than here, albeit from only one of my two servers referenced here (it's the ubuntu 14.04 tarball-based installation). While I suspect that the client is certainly a problem here, I don't know if the server is complicit in anything. Keeping this open for the time being.

Mea culpa, the real culprit was that I was running nextcloud on a linux box but (this is what I forgot) the data directory was a Synology SMB export, which defaults to the windows way of filename case-insensitivity.

As suggested on a synology forum, the fix was to force Synology to edit /etc/samba/smb.conf and append case sensitive = yes in the [global] section.
