Dropbox Linux Application Broken


Problem: I use DropBox’s desktop client for Linux to help keep all of my files backed up and synced across devices (and I’d highly recommend everyone do this, too!). This is awesome when it works, but for the past few weeks, every time I boot up the DropBox client, I just get a red DropBox logo with a warning sign on it saying that it can’t sync my files. What gives? How do I fix this?

Solution: It’s likely that your DropBox process/client doesn’t have the requisite permissions to execute the synchronizer that, well, syncs all your files to their servers. Luckily, this is super easy to fix.
