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...

(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.
~/.dropbox-dist$ strace ./dropboxd
yields a lot of output like this mentioning "The resource is currently not available":

I'm not sure if this is meaningful or indicates a problem.
It's working again.
I ran ~/.dropbox-dist$ strace -f ./dropboxd.

Hey Monika, thanks for keeping us updated.
Happy to see that you were able to resolve this.
This info might also prove useful to other users who may come across this issue, so we really appreciate it.
Make sure to let us know if you need anything else! 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 typemeaning: No such file or folder of this type
What did I do wrong ?
- The command is like this:
cd .dropbox-dist
strace -f ./dropboxd
