My Fedora 17 can't make any software update because Yum seems to be crashed. This is the problem:

Okay, I'll bite. Do you have enough free memory?

I have repaired it. The real problem wasn't the memory. I have enough. The problem was that the Yum Data Base had some "duplicates" or clones of the repos. We need the yum-utils. Normally it is installed. If not, install it with yum install.

And we just have to write this command (as root):

package-cleanup --cleandupes

It will show us the list of "dupes" and ask us for eliminate them. If we agree, just write yes.

If we want to be sure, just write this command to rebuild the Yum Data Base.

rpm --rebuilddb

And that's all.

Well this is odd. How does one install yum-utils if yum doesn't work? Was it installed before this problem occurred? Did you install yum-utils using rpm?

You might have a different problem. You should open a new question instead of proposing a new answer to an existing solved question.

I have the same problem with fedora 19, but package-cleanup --cleandupes shows "No duplicates to remove"
