Dropbox has ended all other filesystems except ext4 on linux. Unfortunately my VPS on Qcloud is not ext4, so I can not use dropbox the last few months. Today I decided to add a data drive which can be formatted as ext4 to get my dropbox syncing back. Below is the steps, thanks to this questions1.
First, remove all dropbox related directories.
rf -rf ~/.dropbox-dist rf -rf ~/.dropbox
Second, install dropbox daemon according to 2. Note that you need to download the tarball and extract it to the desired directory, say /data/db/, manually.
wget -O /data/db/dropbox.tar.gz "https://www.dropbox.com/download?plat=lnx.x86" cd /data/db/ tar xzf dropbox.tar.gz
Third, start dropbox.
Last, link dropbox related directories to home directory in order to using
ln -s /data/db/.dropbox-dist ~/.dropbox-dist ln -s /data/db/.dropbox ~/.dropbox
After all these steps, you can use dropbox again, try
dropbox.py status. :)
