No write access to external micro SD card
I have a x86 tablet where I installed Android x86. I know this is a rater unusual setup, but I don't think the issue is related to this since other apps on the same system do not have this issues to write to the external micro SD card.
Issue
The Android nextcloud client 3.10.1 has no write access to the external micro SD card. The easiest way to prove this is by trying to upload a file to nextcloud. The app then shows a warning that the file system is read only:
Notes:
- The app has all permissions!
- The app never asked me for write permissions on the external micro SD card!
P.S. The bug originally was reported in https://github.com/nextcloud/desktop/issues/1840
* The app never asked me for write permissions on the external micro SD card!
This should be asked…at least something like "wants to access images, etc."?
Can you go to app settings (on android side) and check Nextcloud permission if storage is allowed?
I have the same issue, storage permission is allowed, but I never had to confirm the access to the SD card. This article might be related.

I guess that reading external storage is then just granted.
@caco3 without having access to such a device, I fear that I cannot do anything. In your first screenshot "SD Card" should be the extern storage card? It seems that this is a link (on unix fs), which cannot be resolved by Android?

You are mislead :) That is just an empty file indicating that this is my SD Card. I usually have such a file so I easily see from within every file browser where I am :)

All 3 permissions are enabled (checked it already many times)
Do you know if other apps/user have the same problem on x86? Can you ask the maintainer of this?

No, I am not aware of any other users with this problem. I will try to get more information using the log and the development version of the app.

Without any test device I fear that I can never fix this. x86 seems to be also a very experimental thing.
In my case it is not x86. Also I've seen this issue with at least 3 different phones
To reproduce, just go to settings and change "Storage path" to the SD card, then go to auto upload, and you should probably not be able to configure the "Original file will be..." option
I think this might be only for folders on the SD card, though. The "Original file will be..." option for a SD folder says "kept in original folder, as it is readonly", but it is possible to configure it for a folder on the main memory
Yes, as you are allowed to write into those folders that you create (via storage option), but you are not allowed to delete other files (move is technically a copy & then delete).

Same problem on Samsung Galaxy A6 with Android 10 Nextcloud Client Version 3.13.0
When I try to upload (or auto upload) a file from my SD-CArd (/storage/0000-0000/DCIM/Camera), I can not choose any action for the source file, because the source directory appears to be read-only (Originaldatei wird ... im Original-Verzeichnis belassen, da nur lesbar)
How is the sdcard mounted? I remember that some Android/Vendor offer to mount sdcards differently, e.g. as external or internal storage.

As we have to rely on Android's permission management, I am not sure if we can solve this… (there are file browser that "bypass" this and ask user for temporary permission and then use storage access framework, but this is not a solution we can use, as auto-upload should happen in background without user interaction)

In my case it says "portable storage", and I can actually unmount it and insert it in a different device, therefore I assume it is external.

I don't know how this works, but a few apps asked me to "select" the folder once, to gain access, but after the first time, the permission seems to be granted, and never asked again... I think that granting access once (either when you start the app the first time, or when you setup the auto-upload) is an acceptable solution...
My phone reports the SD-Card under "Portable Storage" (Mobiler Speicher). The SD-Card is writable by the app, because I can use the SD-Card for App-Data.
When I try to upload any file from the SD-Card, then I can't change the Upload Option, because it appears to be read only. But when I try to upload a file from the Nextcloud App directory on my SD-Card (/storage/0000-0000/Android/media/com.nextcloud.client/....), then I can change the upload options.

Do you know an open source app that uses this behaviour? Then we can might adopt this?
One app that does that for sure is SD Maid. Unfortunately it is not open source, but you might want to have a look at the Setup page in their wiki, perhaps you might find something useful there. I'm quite sure I had at least another app that was doing the same thing, but unfortunately I cannot recall which one. I'll let you know if it comes to my mind...
Setup page does not help code wise. Would be great to know the other app. 🤞 that you remember it :-)
c:geo does it AFAIK as well and is opensource. I cant test if I am right and when the dialog comes, but in its settings one can select folders to store the data.

Found it! The app is "Simple Gallery". I just got the permission request while trying to move a file from the internal storage to the SD card.
I hope this helps...
