If your Dropbox stopped syncing because of you use encryption or unsupported file system. This video will help you to fix this issue.
You will be able to sync your Dropbox folder again as well as to make it encrypted. Linux Dropbox stopped syncing on any file system other than unencrypted Ext4 on Nov 7. If you received this message or this email. You are one of the victims as I am.
The solution is, however, pretty simple.
You need to move your Dropbox folder to either unecryptedext4 filesystem or to LUKS encrypted filesystem. The first option is easy to do and I would recommend it for new users. And the second one is for those who care about security and have some Linux experience. It will involve creating a new partition and encrypting it with LUKS. Luckily, Dropbox supports LUKS encryption on Linux. Using another partition is also the only alternative for those who use other than the ext4 file system. Let’s get started! Again, the first option will make your Dropbox sync again but the Dropbox files won’t be encrypted.
This is a simple solution for lazy or inexperienced Linux users. First, quit Dropbox if it is open. Second, I will use some simple terminal commands, because it is much faster than doing the same graphically. Just be careful to follow these commands. I will show the results in the graphical file manager in the end. So, I assume you use the ext4 file system with encryption of your home directory. This is a set up used by Ubuntu, Linux Mint and many other distributions. I also use it in all my systems If you are unsure, check your filesystem type with this command You can see my root folder which also includes my home folder is ext4 type.
If you have a separate home folder, you should see it too. And most likely it is on the ext4 filesystem and if you list the directories one level above your user folder: you should see this. Ecryptfs folder this means your home folder is encrypted with Ecryptfs. And this is unsupported by Dropbox So, the easiest way to make your Dropbox sync, is to go one level up of your encrypted user folder. This part of your filesystem is not encrypted.
You create a Dropbox folder here. Assign its ownership to your current user. These are your user name and group. If you don’t know your user name and group. Run the command and you will get this information. Also make it possible to read, write and execute files in this folder.
Next, copy your Dropbox files here with retention of their change time. This option is very is important! And to be safe, rename the current Dropbox folder to Dropbox-old. If something goes wrong, you will be able to restore all your files from this Dropbox-old folder.
Next, created a symlink to the newly createdDropbox folder in your user folder. I explained symlinks in this video Finally, open your file manager and you should see this Dropbox symlink. Symlinks have this or similar sign on them. If you go to the properties of this folder, you will see that it points to the Dropbox in your home folder outside of your user folder.
Let’s check this folder too. Here it is. So, everything is fine. Let’s start the Dropbox. It is syncing now. If you screw up something, remember that all your original files are located in Dropbox-old folder. And you also can go to Dropbox web interface and here you can show all deleted files and restore them manually.
For the second option, you need to move your Dropbox folder following the same procedure as I have just shown but you move it a LUKSencrypted partition and symlink it to your user home folder. If you don’t have a separate partition which you can encrypt with LUKS, you can shrink your current partition and create a new partition with Gparted.
Next, you encrypt this new partition withLUKS. And move your Dropbox-folder there. I am not going to show all these steps again because I have dedicated videos to each of these steps with good explanation. Also, keep in mind if you use Dropbox on several computers and some of them are unsupported, Dropbox may not sync on your computer even if you do the manipulations described in this video. You need to fix this unsupported file system issue on all computers. Given these complications with using Dropbox on Linux, you may consider trying some Dropbox alternatives.
