Dropbox isn't syncing anymore after upgrading to Ubuntu 20.04

I upgraded from Kubuntu 18.04 to 20.04 a little over a week ago. Since then Dropbox isn't syncing anymore. The icon in the task bar keeps switching between the network folder icon and the box icon (D...

    It's working again.
    I ran ~/.dropbox-dist$ strace -f ./dropboxd.
    It often showed ("Vorgang nicht zulässig" = "activity not allowed"):
    [pid 8640] openat(AT_FDCWD, "/home/monika/Data/Dropbox/Dateien/programme/Videobearbeitung/software/otr-verwaltung3p/data/tools/intern-VirtualDub/wine/dosdevices/z:/usr/lib/jvm/java-1.11.0-openjdk-amd64/legal/java.compiler", O_RDONLY|O_NOATIME|O_CLOEXEC|O_DIRECTORY) = -1 EPERM (Vorgang nicht zulässig) zu sehen
    I moved the entire folder Videobearbeitung out of the Dropbox folder be on the safe side and restarted Dropbox.
    Immediately things improved, a notification showed "90 files deleted from Dropbox", my husband's PC showed "9 files changed" for a shared folder and after a while the systray icon stopped blinking and just showed the box (without arrows).

    (The weird thing is that I had deleted all local files at one point and Dropbox had downloaded them - including the offending one.)

    The "echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf; sudo sysctl -p" probably also was part of the solution.

Hi MonikaE,

I have the exact same problem stemming for the same background (upgrading from 18.04 to 20.04), but trying your solution here is what I get :

pier@pier-Buroo:~/.dropbox-dist$ ~/.dropbox-dist$ strace -f ./dropboxd.
bash: /home/pier/.dropbox-dist$: Aucun fichier ou dossier de ce type

meaning: No such file or folder of this type

What did I do wrong ?

    The command is like this:
    cd .dropbox-dist
    strace -f ./dropboxd

      MonikaEthanks,

      But I get this :

      Unable to monitor entire Dropbox folder hierarchy. Please run "echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf; sudo sysctl -p" and restart Dropbox to fix the problem.

      I did as suggested but to no avail. Do you have an idea ?

        Have a look at the file /etc/sysctl.conf. Is there an entry "fs.inotify.max_user_watches=100000"? And no other entry with "fs.inotify.max_user_watches=..."?
