Hi!
Summary: Try to prevent a package from being updated/installed from
repositories regardless of the package management tool you use. As it
seems, then only way you can do this is to exclude it from the
repositories themselves inside their configuration file in
/etc/yum.repos.d/, because these are the only common settings between
all three (yum/dnf/PackageKit). TBH, I'm not sure about PackageKit, but
I feel that it don't read /etc/dnf/dnf.conf as it doesn't use DNF but
its backends. This is fine if the package is in a single known
repository, but what if it is in 3 repositories that you might not be
aware of all of them?
More details:
As you might already know, nvidia drivers in RPMFusion F21 repositories
doesn't work for all nvidia cards. In one system, I finally installed
akmod-nvidia from RPMFusion F20 repositories which worked fine. Soon
after I realized that I should exclude akmod-nvidia and dependencies
from F21 repositories. I added "exclude=*nvidia*" to /etc/yum.conf as I
was lazy to check which repository these packages come from. But then I
noticed that dnf doesn't consider it excluded. Then I thought that
probably PackageKit doesn't use dnf.conf too. So, how should I excluded
these packages? Well, these were in rpmfusion-nonfree-updates
repository, so I added the exclude directive there. Then I found that I
should add it to rpmfusion-nonfree repository too. However, since I use
yum-plugin-local I also have a local repository (I actually copied the
repository from another system, so it was enabled on this system so that
I could install software from it) which also included these packages.
Therefore, I should exclude "*nvidia*" in 3 repository configuration
files to make sure (hopefully!) that these will not be installed by any
package manager I know.
Suggestion: Please add a single configuration file to configure common
package manager options (Specially between DNF and PackageKit, which are
there to stay). As I mentioned in "F21 downloads repository metadata in
3 places!" thread, Fedora package management should be consistent and
integrated; and the current situation is really frustrating. If I want
to exclude some packages, I should be able to do it once for all. If I
want to disable automatic download of metadata/packages, there should be
a single place where I can define my desired package management policy.
If I want to specify default metadata_expire timeout for all
repositories, there should be one place to do it. There really should be
a single package management policy that must be respected by every
package manager in Fedora, specially the main ones: DNF and PackageKit
(and currently Yum).
