I am trying to update my FC3rc3 installation using yum. I've done a yum install yum. Everything appears to work OK until I receive this error: <snip> Update: python.i386 0:2.3.4-11 Update: python-devel.i386 0:2.3.4-11 Update: system-config-packages.noarch 0:1.2.20-1 Update: up2date.i386 0:4.3.47-5 Update: up2date-gnome.i386 0:4.3.47-5 Update: xinitrc.noarch 0:4.0.14-1 Is this ok [y/N]: y Downloading Packages: unsigned package //var/cache/yum/development/packages/gthumb-2.4.2-4.i386.rpm <end of snip> So then I try to exclude it from the update and because it doesn't find a match for it, it won't proceed with the update: <snip> Could not find update match for --exclude=gthumb-2.4.2-2 No Packages marked for Update/Obsoletion <End of snip> "Packages" I've tried: gthumb gthumb-2.4.2-2 gthumb-2.4.2-4 gthumb-2.4.2-4.i386 gthumb-2.4.2-i386.rpm up2date has a similar sort of problem in that it will error out because one package isn't signed. How do I get my update done ? What am I missing about using --exclude ? Thanks
