I have been effected by this bug for a long time. In the end, I resorted to using dropbox, which works reasonably well (with no web access or course). Recently, dropbox access has been blocked at work, prompting me to look at this again.
I tried most of the things mentioned above, to no avail. Then I read some other bug reports with complaints about conflicts in templates (templates do not show up in note lists, so cannot be deleted manually. So, I deleted these manually with the following procedure quit tomboy Romove all notes from web server. I found the easiest way to do this was to sync an empty tomboy instance to the web. Move old tomboy notes to backup: mv ~/.local/share/tomboy ~/.local/share/tomboy.bak Restart tomboy, which will create a new library. Delete all notes (start here etc) Set up sync to ubuntu one web account and sync. Check online at ubuntu one to see that all notes are gone. quit tomboy Then, clean out all old template notes from backup library cd ~/.local/share/tomboy.bak locate old template notes, those that have been renamed in previous sync attempts. grep "Template (old)" * remove the offending notes (rm ...) Move library back to where tomboy expects it rm -fr ~/.local/share/tomboy cp ~/.local/share/tomboy.bak ~/.local/share/tomboy restart tomboy, and sync to ubuntu one. This seems to have fixed my system now, and I have 419 notes synced to the web.
