This saves a files with the name “1545246669” and no extension. If you rename the file, it is the correct one, so it purely an issue with the name and extension, not corruption of the file.
Nextcloud version : 15.0.7 snap package
Operating system and version : Ubuntu 18.04 (VM on Hiper-V)
I can not say for sure, this bug was immediately after installation or appeared later. But when I try to download the version I need, everything happens exactly as in srhogg. Perhaps this is somehow related to the fact that I mounted the 1TB drive as /var/snap/nextcloud.
It is definitely unrelated i think to mounted drives. I had had the issue prior to a mount. Even on the newest version 16 this is still a problem and is keeping us from even releasing Nextcloud internally to people. I think this issue was introduced at NC 15.
