Fedora: killed yum

Hello,

I was installing compiz-plugins in terminal when I had a power cut. Now whenever I load add/remove programs I get this error:

How can I fix yum?

Well, the error message is, I believe, telling you that the cache data base was broken by the crash. I've never had this problem, but what I'd try first is to see if yum could be convinced to start a fresh cache.

Try (as "root") a yum clean dbcache to see if that might help. (Look in man yum for other "clean" options.)

Anyhow, I looks more like a data problem than a yum problem.

Also, you could try (again, as "root") a touch /forcefsck followed by a reboot to force a full file system check. That might be able to fix some problems.

"yum clean dbcache" worked.

Thanks
