Summary of the issue you are facing:
When editing a Markdown file in my Notes folder, opened through the desktop client (using nautilus-nextcloud), the local file became read-only.
I later found it that the file was locked in NC through the files_lock app, which I don’t remember installing.
Steps to replicate it (hint: details matter!):
-
Right-clink on a synchronised markdown file in Nautilus, chose Nextcloud → Open in browser
-
Browser window opens, edit the file a bit.
-
Notice that write permission disappears from the local file.
-
Close the browser window, and notice that the file doesn’t return writeable.
The problem appears to be that the files_lock app has been activated, or changed, when upgrading from NC33 to NC34, and I found my files going read-only whenever I had opened a note in the Text app through the desktop client, but not if I opened it through the web interface.
A message appeared in the web interface that the file was locked by the Text app, but there was no obvious way of releasing the lock. Opening the Text app in the web interface, and exiting, didn’t release the lock.
If there is a bug in there, it seems to be in the interaction between the desktop client, the Text app, and the files_lock app. When the Text app is in a detached browser windows, it doesn’t release the lock when the window is closed.
I’ve disabled the files_lock app, and I can work as before, mostly on my local files, but opening the editor in NC through Nautilus and the desktop client, as I need.
This worked as expected in NC33, and the changed behaviour arrived with the upgrade to NC34.
