Unable to start yum
 

I was going to use yum to update a software package, and I was confronted with the following error:

Component: Software Manager
Summary: TB9f78d0ec main.py:244:execute:DatabaseError: database disk image is malformed

Traceback (most recent call last):

DatabaseError: database disk image is malformed

Local variables in innermost frame:

parms: ()
SQL: select * from packages WHERE arch != "i686" AND arch != "i586" AND arch != "i486" AND arch != "i386" AND arch != "noarch"

What is the cause of this, and how do I fix it? Thanks.

strange...
 

Sometimes when you do a ctrl + c , while yum is setting up the install processes, you get such wierd errors. Usually a restart is enough. If not try "yum clean all" as root. Try it and let me know.
