I see the same error with the 2.5.1 client and Nextcloud 14, although in my case it is not confined to large uploads: it also occurs with downloads of large numbers of files and directories (in the thousands).

I see the above-described behavior during uploads (i.e. some files upload and then the client returns the error). In the download case, however, the client returns the error during the scan for server-side changes, and then begins a new scan for changes from scratch. This prevents the sync from ever completing because it starts over each time. The error appears non-deterministically (i.e. it is not triggered by specific files or folders), but in my case will always eventually occur with large numbers of files needing to be synced.

The issue does not occur with the nextcloud client version 2.3.3 using the same server and the same client systems.

[sseneca]

Yeah, I can confirm that using client version 2.3.3 along with NC 14 works fine.

[LukasSliacky]

Hm, i can't find 2.3.3 for Ubuntu 18.04 and when i can use OwnCloud client, i have problem with dependencies.
Please, have somebody experiences with install older clients on Ubuntu 18.04?

Have you tried this? I don't have access to a machine running Ubuntu but just search downgrading packages in Ubuntu online and you should find something.

[LukasSliacky]

Yes, but on Ubuntu 18.04 i have problem with dependencies. Maybe when it would be downgrade more packages will be installing okay. But i am afraid it would be more problems for my Ubuntu.

[AlexMV12]

I have the same problem with 2.5.1 and I can confirm that with a server with NC 15, the client version 2.3.3 doesn't have this problem.

[felipeespic]

I have exactly the same problem uploading 45G in Ubuntu 18.04LTS, client version 2.5.1.

It worked for me by installing this library, and then this Nextcloud client by the command sudo apt install <package>.deb. That shouldn't affect your Ubuntu install.

[LukasSliacky]

@felipeespic Man, it works great!
Really thanks for your hint.

[Bleuzen]

Since downgrading the client works, maybe this is not a server bug, but something client side? Should we open an issue on the desktop client repo here on GitHub?

[jdefoe2]

Hello, I'm really happy to have found this thread. I recently set up NextCloudPlus on a Raspberry Pi 3B and was having this (and several other) errors when trying to sync a large amount of data (~280GB, ~200,000 files) from a Linux client (Ubuntu 18.04) running the NextCloud 2.5.1 client. Installing the older library/client and running that instead seems to have solved the problem -- at least the sync is starting without issue. I will post an update if I run into any trouble. Seems like it's definitely a client-side problem!

I've opened an issue on the client repo: https://github.com/nextcloud/desktop/issues/1025

edit: I didn't actually mean to close the issue here, by the way. That was an accident, I'll reopen it if I should.

Hello all,
In my case, it was a server problem.
I have solved this problem “PROPFIND Reply is not XML Formatted” by replacing NextcloudPi by a clean install of Raspbian and Nextcloud. Now, It works like a charm.
Don't forget to modify the php.ini to increase the upload_max_filesize.

[mamojdick]

upload_max_filesize

what value did you put?

I solved this issue (as well as /nextcloud/desktop/issues/908 ) for me on Ubuntu 18.04 by using the 2.3.3 appimage : https://download.nextcloud.com/desktop/releases/Linux/Nextcloud-2.3.3-x86_64.AppImage
