I just installed linux fedora 16. When i want to view my software packages in the "Add/Remove software" it doesnt show any packages. it give the following error when i click on the "Package Collection" tab:

The group list was invalid
The group list could not be loaded
Refreshing your cache may help, although this is normally a software error.

that was the error.
I have already cleanes my cache and i did a system update.

How can i fix this so that it shows my packages.

note: i encrypted my disk at the instalation setup.



Try this. open a terminal and become the root user (using su or sudo) then execute the following two commands and it should refresh the YUM distribution cache.

yum clean all
yum list

You should get a list of all applications available via YUM and your add remove packages application should now be working.

Rebuild the rpm database? This is long and dangerous.

run /usr/sbin/packagekitd before
