Package Manager Failing

Hi,

Apologies if posted on the wrong forum, but I am a Linux n00b. My problem is that today Package Manager is freezing, I goto "System" -> "Add / remove programs" like normal and get the normal Package Manager screen with the Retreiving Software Information progress bar. Problem is that the progress bar gets to about 25 percent and then hangs indefinetly.

I have left it for a couple hours a few times but the same thing happens. The only changes made today were following this to customize the desktop.

Upon killing the process i get the following error report :

Component: pirut
Summary: TB7fe27411 Progress.py:77:hide:AttributeError: 'NoneType' object has no attribute 'set_cursor'

Traceback (most recent call last):
File "/usr/sbin/pirut", line 476, in <module>
main()
File "/usr/sbin/pirut", line 472, in main
pm.run()

self.dialog.window.set_cursor(None)
AttributeError: 'NoneType' object has no attribute 'set_cursor'

Local variables in innermost frame:
self: <pirut.Progress.PirutProgressCallback instance at 0x85d530c>

Help, any ideas???

TIA

UPDATE

sudo yum list | less returns "Metadata file does not match checksum"

Have tried

sudo yum clean metadata

sudo yum -y remove yum-fastestmirror

 

So it would appear that a simple:

sudo yum update

solves all my drama's, :lol: :lol: :lol: :lol: u gotta laugh :roll:
