how to block one package from upgrading
 

Hi,
I installed OpenOffice.org from the OOo website (I'm not using the Fedora package because I need the one provided by Sun) and now I would like to block yum from upgrading OOo. Is there any way to block the upgrading of a specific package?
Thanks,
a.

man yum.conf
 

Look at the manual page of yum.conf (/usr/bin/man yum.conf) there's a line exclude there which u can use to exclude packages from install or update.
Example in the file /etc/yum/yum.conf or for a specific repository /etc/yum/repos.d/fedora(-updates).repo

exclude=openoffice-*

for multiple exclusion seperate by space

exclude=openoffice-* kernel*

Thanks! That helped!
