I got some help from support. The key piece was to run "chattr -R -i ~/Dropbox" which revealed the problem files. I had created symbolic links from my dotfile settings in .config, .themes, and .local and placed the actual files in dropbox folders so that some of my settings would get backed up to dropbox. One of the applications put unchangeable files in dropbox and that is what caused the problems. Since I reinstalled fresh, once I was able to find the problem files via chattr and move them out of Dropbox, syncing resumed and is now fixed.

does the trick

TL;DR

chattr -R -i ~/Dropbox 2> /dev/stdout|rg -io '/home/CHANGEME/Dropbox.*'
