Dropbox has stopped working on my 16.04 Ubuntu

Dropbox has stopped working on my 16.04 Ubuntu.
When I try to start it in bash, this is the
terminal output:

I’ve tried the suggested reinstall but the problem remains.

How to fix non working Dropbox icon on Xubuntu 14.04 LTS 64?

A few hours ago the dropbox icon in Xubuntu 14.04 stopped working.
The icon is black with a red slashed zero. I cannot click on it to bring up the dropbox menu. I believe there was an update right before this happened.
I reinstalled then purged dropbox. I even deleted all associated files and hidden folders and after I installed it again. Still, the icon is not working. Tried to stop and start the service… again nothing.

How to change Dropbox directory on Ubuntu 16.04 outside of encrypted home folder

In November this year, Dropbox will stop sync in case home folder is encrypted (full disk encryption is supported). I have tried to move synch folder outside /home to folder on the Ext4 partition but every time I try only get a message that I need to move my Dropbox to the partition with the compatible file system and that is Ext4 supported (well well I use Ext4).

I have tried many things but on setting up dropbox up it is always set up in the user’s home folder and after that, I am not able to change it.

Is there any solution other than switching to full disk encryption?

How to avoid duplication when using Apex Dropbox API Framework or any other Frameworks/SDKs?

BACKGROUND

I need to implement an integration with Dropbox using its REST APIs. I don’t want to reinvent the wheel so I decided to use Apex Dropbox API Framework. Although it’s a bit outdated (it works with v1 Dropbox API), I found the framework to be really useful.

QUESTION

In the examples – Dropbox Sample Apps, I found that both the DropboxTestHarnessController.cls and DropboxAccountController.cls use the same routine to get a valid connector and dropbox client. Below are some part from those classes:

DropboxTestHarnessController.cls

private void init()
{
    if (connectorService != null)
    {
        String msg = connectorService.validateConnector();
        validConnector = String.isEmpty(msg);
        if (!validConnector)
        {
            error(msg);
        }
        else
        {
            info('Successful authentication. The '' + connectorService.Connector.Name + '' connector is being used for authentication.');
        }
    }
    else
    {
        error('Dropbox connector not found.');
    }
}

DropboxAccountController.cls

private void init()
{
    if (connectorService != null)
    {
        String msg = connectorService.validateConnector();
        validConnector = String.isEmpty(msg);
        if (!validConnector)
        {
            error(msg);
        }
    }
    else
    {
        error('Dropbox connector not found.');
    }
}

Both these pieces are nearly the same. I understand that the code given in those classes are for example purposes. Whereas my concern is how do I avoid code duplication in my project. Let’s say I need to use the dropbox service from 4 apex controllers and repeating the same initialization routine doesn’t look good.

I was thinking of creating another service layer that would be responsible for initialization, but I am not 100% sure that is a correct approach. Again I don’t want to reinvent the wheel here and I believe there should be a standard solution (pattern) to this kind of problem, yet I haven’t found anything on the Internet that explains it clearly.

iPad 10 locked up trying to open HTML file from dropbox

My iPad 10 iOS 12.0.1 locked up when opening an html file from Dropbox. Flashing sign: “Leaving Dropbox This file is trying to open another app. CANCEL CONTINUE.” Cancel or continue buttons are not functioning. I can’t clear this. I’ve tried tapping, closing and rebooting both Dropbox and the iPad but none of them clears this error. I also tried to update the iOS software.

Can’t Move the Dropbox Folder to Ext4 or NTFS partition

I’m using Ubuntu 16.04 LTS. In response to the change in dropbox file system support, I created a new partition on my hard drive to store my dropbox files in. It’s 2 GB larger than my maximum dropbox space.

My main partitions are all Ext4, but my home partition is encrypted which apparently doesn’t work. This new partition was made without any obvious encryption option.

Trying to move the dropbox folder, using dropbox > preferences > sync > dropbox folder location, and selecting a folder on my new partition returns a system incompatability error (see screenshot)

I reformatted the partition to NTFS, but dropbox refuses to move the folder, with the same vague error. I looked through the circuitous FAQs this error links to, as far as I can see there’s no other special circumstances to my setup. I’m just a guy using linux who doesn’t want to reinstall his entire OS, and is about ready to cancel his dropbox subscirption.

Dropbox asks Authentication is needed to run `/usr/sh’ as the super user

This question has been asked several times, but the standard answer does not apply.

Current system: Ubuntu 18.04, kernel version 4.15.0-29-generic. But it started on – I think – 16.xx.

The system comes with this question at user login. A simple Cancel is fine for Dropbox to do the thing it is supposed to do. Occasionally it asks 3 times, somewhere in a login session.

The standard advice on the forum is to change the according line in /usr/bin/dropbox into PARENT_DIR = os.path.expanduser(“~”), but that is already how it comes for the last few years. I install each release from scratch on alternating root partitions, so no left-overs. /home is on a separate partition, so that’s a place for a possible left-over. The message has recently been absent for about 3 weeks, but after the latest kernel update it’s back. Note that the system now asks for permission to execute /bin/sh, no longer for /usr/bin/dropbox.

Your help would be appreciated.

How do I remove the Dropbox entry from the Windows Explorer navigation pane

To start, I have already uninstalled Dropbox from my system. However, as the title suggests, the navigation pane entry resides, rather annoyingly, and seems to be the cause for a slowdown in Windows Explorer’s performance.

enter image description here

If I click the entry I get the standard resource unavailable message.

enter image description here

I have already searched for the issue and followed guides posted on the dropbox forum and on reddit and tried this .Bat program (thanks to @Yisroel Tech). None helped me solve the issue as the Registry Keys that they mention {E31EA727-12ED-4702-820C-4B6445F28E1A} don’t exist anymore (I assume, because its no longer installed).

I have also restarted the PC and separately, Windows Explorer, in my efforts.

Any other ways to remove the item from the Navigation Pane?

EDIT:

There aren’t any options in the right click menu to remove the item.

I’ve now tried to add the key {E31EA727-12ED-4702-820C-4B6445F28E1A} with a REG_DWORD of System.IsPinnedToNameSpaceTree and value of 0 to the locations
HKCRCLSID, HKCUSoftwareClassesCLSID and HKCUSoftwareClassesWOW6432NodeCLSID to no effect.

I also tried searching the location HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerDesktopNameSpace for something relating to Dropbox but there isn’t anything.
