Comment 6 for bug 473616

You look at what version is installed with:

$ dpkg -l libcouchdb-glib-1.0-1

and

$ dpkg -l evolution-couchdb

Reinstalling 9.10 won't fix the problem, since you need to use the latest packages for those 2, so please, if the version numbers are lower than the ones in https://edge.launchpad.net/~ubuntuone/+archive/beta, install the packages from that PPA. To install them, just do:

$ sudo vim /etc/apt/sources.list

and add, at the end of the file, these 2 lines:

deb http://ppa.launchpad.net/ubuntuone/beta/ubuntu karmic main
deb-src http://ppa.launchpad.net/ubuntuone/beta/ubuntu karmic main

then, on a terminal:

$ sudo apt-get update
$ sudo apt-get upgrade

once the upgrade has finished, log out and log in again, to make sure you run the latest version of the packages
