Web upgrade with lost+found in data directory does not work

[herring-swe]

Steps to reproduce

1. Upgrade nextcloud from 11.03 to 12.03 from administrators panel
2. Upgrade fails when making backup due to read error of "lost+found" in nextcloud/data directory

Expected behaviour

It should ignore lost+found folder

Actual behaviour

Upgrade stops.
After setting chmod o+rw on lost+found it works (but I shouldn't have to)

Server configuration

Ubuntu 16.04, apache.. ext4 fs of course :)
The rest shouldn't matter.

Lost+Found should not be there. The data folder is supposed to be controlled by just Nextcloud. I assume you are mounting this. In that case, it is best to not use root level of the mount but create a subdirectory within and use this as data folder. However changing the datadir in Nextcloud's config is not supported, you'd want to keep the path intact.

I'd say nextcloud should support having a root mount as a data dir, or root installation folder. Since it's for file-sharing and thus might need a large separate filesystem.
Currently it works perfectly and only trouble is with the upgrader, which can easily detect and skip this folder.
I could set the datadir to be elsewhere but my experience with other software says things break especially in upgraders which might not probe for the correct location of dirs (staring at pydio).

This is an updater issue and was already reported there.
