Bug 21328

[rolf@p8z68 gifs]$ rpm -qa | grep dropbox
python3-dropbox-3.41-1.mga6
python-dropbox-3.41-1.mga6
dropbox-servicemenu-0.16.1-5.mga6
dropbox-2015.10.28-1.mga6.nonfree

The right-click menu shows a Dropbox sub-menu but the items, e.g. "Generate public URL..." don't work.  This is under the Public folder, where this worked before, in MGA4, kde4.  The message copied to klipper is "Couldn't get public url: Unknown Error"

As well,

[rolf@p8z68 gifs]$ pwd
/home/rolf/Dropbox/Public/gifs
[rolf@p8z68 gifs]$ dropbox puburl banana.gif 
Couldn't get public url: Unknown Error
[rolf@p8z68 gifs]$

This is the case always, after various re-installs of programs.  I wrote about some investigation I tried here: https://forums.mageia.org/en/viewtopic.php?p=69034#p69034

For one thing,

[rolf@p8z68 gifs]$ rpm -qf `which get_dropbox_folder.sh`
dropbox-servicemenu-0.16.1-5.mga6

and, in that script, which returns the following fatal error when run from CLI, there is:

# which database have we got?
  if [ -f "$HOME/.dropbox/config.db" ]
  then
    local DBFILE="$HOME/.dropbox/config.db"
    local DBVER=$( "$SQLITE3" "$DBFILE" 'SELECT value FROM config WHERE key="config_schema_version"' )
  elif [ -f "$HOME/.dropbox/dropbox.db" ]
  then
    local DBFILE="$HOME/.dropbox/dropbox.db"
    local DBVER=0
  else
    fatal "Dropbox database not found, is dropbox installed?"

but there is an intervening directory in the current dropbox:

    [rolf@p8z68 .dropbox]$ find . -name config.db
    ./instance1/config.db

more verbiage at the linked forum thread.
