@asubramanian1 Sure, I take it I’ll need to install GDK for that? I don’t have it set up yet, as I just edited the commit above here in the web UI.

This fixes a typo in the 2FA settings: ”an one time” -> ”a one time”

Nextcloud is somehow different from other apps in this regard, as no other light (white) apps on the same device have this issue. For instance, here’s Play Store on my affected device (running Android 6.0.1):

Also, I seem to recall this only having started to affect Nextcloud quite recently, perhaps sometime in the past month or so.

Switching to dark mode is a workaround on my device at least (there the Android buttons are light-on-black). I can also confirm that the issue doesn’t affect my newer devices with newer Android.

No, I haven’t (and wouldn’t know how).

Yes, this is still present in 20.04 with printer-driver-cups-pdf 3.0.1-6, limited to original reporter’s case of having the symlink point to another filesystem; if I point ~/PDF to, say ~/tmp/PDF (without crossing filesystem borders), the PDF is created without issue, whereas having ~/PDF linked to /media/$USER/$USB_THUMBDRIVE/PDF/ does still cause it to fail:

For me this seems to have resolved itself since Ubuntu-distributed Firefox was updated to 84, though for all I know, it may have just coincided with some change implemented at Twitter’s end.

@agnivade Oh I see, so it’s a result of conflicting indicators (”away” vs. being active) from the user. I’m trying to recalibrate my expectation based on this, but it’s difficult.

My immediate thought is perhaps (in the problematic case) sending the notification, but then clearing it only once I start typing (typing appears to have an event associated with it, at least based on the logs) would be better than the immediately clearing ghost notification, but you’re right, this is more complicated than immediately apparent.

Some UI/UX design wizardry would probably be needed to eliminate the possibility of mixed user signals, if at all possible. I don’t have a good solution for now, so feel free to close the issue if you deem it appropriate.

Yup, your description of the issue is exactly right @agnivade, and thanks for looking into this!

I set up the two users in parallel windows. Sending a normal message as userB this way does not trigger the issue (I do get a notification on userA’s phone, but it doesn’t go away by itself), but that’s because userA’s window is (obviously) not active, since I’m typing in userB’s window. The notification is only cleared once I activate userA’s window.

But I can trigger the issue by using (for instance) /echo 'hello A' 4 instead (as userB), then hopping on to activate userA’s window during the 4-second delay, so that userA’s window is active when receiving the message. That’s the crucial bit: the receiver’s window is active when receiving the message. If his status is ’Online’, there’s no push notification (as expected), but if it’s ’Away’, that’s when I get the ghost notification.

Here’s server log and MPNS log during one minute where (as userB) I first send a normal message, then (at about 30 seconds) using /echo.

Yes, this is still reproducible here with the current server (v5.29.1).

Here’s the server log and MPNS log during which

1. I switch log level from error to debug
2. I send one ”hello” message to a bot (from the web UI)
3. the bot responds with one message
4. I switch log level from debug back to error
