If you're experiencing issues with Dropbox stuck on starting, don't worry, it's a common problem that can be easily fixed.
One possible cause is a corrupted cache, which can be resolved by deleting the Dropbox cache files. This will force Dropbox to recreate the cache, potentially resolving the issue.
To access the cache files, you'll need to navigate to the Dropbox folder on your computer, which is usually located in the user directory. From there, you can delete the cache files and try restarting Dropbox.
Another possible cause is a problem with the Dropbox installation, which can be resolved by reinstalling the application. This will overwrite any corrupted files and potentially resolve the issue.
Troubleshooting
If you're stuck on the Dropbox login screen, try closing the app and reopening it. This simple step can often resolve the issue.
Make sure you're using the latest version of Dropbox. If you're not, update the app to the latest version.
Dropbox may be experiencing technical difficulties, so check the Dropbox status page to see if there are any known issues.
Recent Discussions

I've noticed that some users are experiencing syncing issues with Dropbox on their Windows 11 computers.
Dropbox isn't syncing on some Windows 11 computers, as seen in a recent discussion where a user reported the issue just 7 hours ago.
Restarting the Windows device seems to resolve the syncing issue for some users, as one user noted that Excel files only sync after restarting their device.
Uploads are painfully slow for some users, not just on the Dropbox website but also on the desktop app, which is a common issue that's been reported recently.
Some users have reported that files on the Dropbox site aren't syncing to the Dropbox desktop folder, but one user was able to resolve this issue, so it's likely a temporary glitch.
Here's a summary of the recent syncing issues reported by users:
- Dropbox not syncing on Windows 11 computers
- Excel files syncing only after restarting Windows device
- Slow uploads on Dropbox website and desktop app
- Files not syncing from Dropbox site to desktop folder (resolved by one user)

Sync Stuck on Ubuntu
If you're stuck with the "Syncing ..." message on Ubuntu, try running Dropbox from the command line. This might give you a hint about what's going on.

The issue is often caused by a setting in Ubuntu called fs.inotify.max_user_watches, which has a default value of 100000. This can lead to syncing problems in Dropbox.
To fix this, you can add a line to /etc/sysctl.conf by running the command "echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf". This should be followed by "sudo sysctl -p" and a restart of Dropbox.
However, this fix might not be permanent, and the problem can occur again after a reboot. In this case, you'll need to run "sudo sysctl -p" and restart Dropbox manually.
Increasing the value of fs.inotify.max_user_watches to 500000 has also been reported to fix the issue.
Error Causes
Dropbox stuck on starting can be frustrating, but let's break down the possible causes.
A short-term system problem could be the culprit, and restarting your computer is often enough to resolve it.
Outdated software can also cause issues, so make sure you're running the latest version of Dropbox from the official website.
A corrupted installation might be the problem, and reinstalling Dropbox can give you a fresh start.
Overly cautious security software might be interfering with Dropbox, so try disabling it temporarily to see if that's the issue.
Conflicting background processes can sometimes cause problems, so find and close any unused programs that might be causing issues.
Dropbox requires a stable internet connection to work, so make sure you have a strong signal and check your internet connection.
Sync issues can also cause Dropbox to get stuck on starting, and stopping or restarting the sync function might resolve the problem.

Fixing Issues
If you find the Dropbox desktop app stuck on starting, try using Dropbox as an administrator on Windows 10. Right-click on the icon and select "Run as Administrator" to confirm that Dropbox has been successfully activated.
For Linux users, unlinking your account from the Dropbox application and then relinking it again can solve the problem quickly. Be aware that you might be deleting files that haven't been synced yet.
The root cause of the issue can be due to the device limit on a free account, so check the "Devices" section on the Dropbox website to remove old devices. If that's not the issue, try increasing the fs.inotify.max_user_watches value to 100000 or more, as suggested by a user who had to increase it to 524288 to fix the problem.

If you're experiencing issues with Dropbox, you're not alone. One common problem is when Dropbox partially syncs, but then gets stuck.
Leaving the machine running for a long time can sometimes resolve the issue. However, this might not be a viable solution if your system's resident memory usage keeps growing, eventually leading to system crashes.
Dropbox's indexing process can be slow, especially on older machines. For example, on a rather old HP laptop, Dropbox can take up big time in the CPUs, using around 10% of the system's resources.
Ran into this issue recently on a 20.04 system, and starting Dropbox from the command line revealed some useful information. The command output suggested that increasing the device limit might be the solution.
Increasing the device limit by running `sudo sysctl fs.inotify.max_user_watches=100000` might be necessary, especially if you have a large number of files in your Dropbox. However, this value might need to be adjusted depending on the number of files you have.
To resolve the issue, try unlinking your Dropbox account from the application and then relinking it again. This can often resolve the problem quickly.
