Every day Dropbox shows me a dialog box to confirm its update to the new version. I confirm it every day. It downloads some files, unpacks and installs them (at least, it shows progress bar). In the end, the dialog just disappears. No confirmaiton of successful install and no error message. So today I checked it in the command line.
I run dropbox update. It downloads and installs some files, and in the end reports success. I check the version, and it's the same version. If I run dropbox update again, the same repeats. The version doesn't become newer.
Why would Dropbox ask for an update every day if there's no newer version?
