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).
Hi, I understand the frustration. On the other hand, I personally hate
anything that is centralized. Just an idea: what about a simple
modular tool (maybe installed by default) which would be able to set
options like this at all the places? Potentially it could be able to
synchronize a subset of settings between given programs.
While I prefer the centralized approach (and also consider your approach
still a centralized one), but whatever works is fine with me.
