I am experiencing file sync failure in Ubuntu One at 12.04 for about one month It happened without any notice and still continues.
<> When I launch Ubuntu One, File Sync does not start. When I click "Sync File" button in top right, it says "auth failed (AUTH_FAILED)" and gives dialog "I am sorry but we need to close Ubuntu One due to erros" (message in Japanese, so this is my translation), with the following output:
UnauthorizedError u'\u30db\u30b9\u30c8\u306e\u8a8d\u8a3c\u304c\u5fc5\u8981\u3067\u3059' u'OAuth required (mandatory).'
(It seems that these strings are Unicode character, possibly UTF-8 string. It that Japanese file name?)
No account information and Current Service displayed. By clicking "Edit Service Online" button, web page shows only "OAuth required (mandatory).", possibly authentication error.
<> I re-installed all related packages to Ubuntu One (tried to remove settings), and produced no improvement. I also removed all files possibly related to Ubuntu One manually by:
sudo rm -rf ~/.local/share/ubuntuone rm -rf ~/.cache/ubuntuone rm -rf ~/.config/ubuntuone mv ~/Ubuntu\ One/ ~/Ubuntu\ One.orig/
and restarted computer. These procedures brought no betterment for this inconvenience.
Moreover, my another Ubuntu instance (also 12.04) met the same Ubuntu One error today and it still continues.
Does anyone suggest solution or at least the reason? Thanks,
