Debian's Synaptic has a cool option which allows you to permanently ignore updates for a single package. It recently occurred to me my 3G modem doesn't work with new ModemManager/NetworkManager packages, so while the bug is fixed, I'd like to stay with an older version of those packages. Currently I either have to remember unchecking the updates from the software update UI manually every time or I have resort to command line and use `yum update --exclude foo bar`.
Such an option would also prevent the update icon from appearing in the systray if the ignored packages are the only updates available.
We moved the upstream bugtracker to GitHub a long time ago. If this issue still affects you please re-create the issue here: https://github.com/hughsie/PackageKit/issues
Sorry for the impersonal message, and fingers crossed your issue no longer happens. Thanks.
