I have been using Calibre for about a month, and after a reinstall of Ubuntu 9.10 (Karmic Koala) I reinstalled Calibre and now it won't let me add any books at all, I even tried some that I know worked previously and they dont' work.
I get this error message:
WARNING: Failed to read metadata: Failed to read metadata from the following:

My calibre installed version is 0.6.13. The Calibre website says that 0.6.37 is the latest version, however there are no download links for linux, and my 0.6.13 is the version in the Karmic Koala repositories.
I've looked at other similar posts, and this is different in that I always get this error, no matter what. Also, as there are no links to download previous versions (or newer ones) I can't do that... nor can I find an apt line anywhere for a calibre specific repository.
Anyone have any ideas/suggestions on how to fix this issue?
