[Solved] GNOME Software Center Frozen in Fedora

[Solved] GNOME Software Center Frozen in Fedora

Has this ever happened to you?  When you attempt to open Fedora‘s GNOME Software Center, you just see the message “Software Catalog is being Loaded” ….forever! At first glance, it looks like the Software Center is frozen, but you can actually move and close the application. Re-opening the Software Center doesn’t make any difference either since the same message appears and none of the software…

Fedora user? Full root directory? Blame PackageKit

Looking at a system which I have been upgrading by a variety of mechanisms from F14 to F27 I noticed that its root directory (which I had on a separate partition for convenience) had started to become rather full. Muddling about with

du -sh -d 1 $name-of-directory

it became obvious that the prime bloat was all in /var/cache/PackageKit. Within it were directories for each of F23 to F27 taking up roughly 23GB in total. Some frenzied Googling turned up this bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1306992 Although the consenus seems to be that the problem manifests when using both dnf and PackageKit I am pretty sure that I only used dnf on this system. As hughsie notes PackageKit is only going to be in maintenance mode and everyone is scrambling to get Atomic and ostree in to shape. Meanwhile the solution seems to be to edit the PackageKit.conf to stop it cacheing downloads of RPMs. Then the older directories F23 updwards need to be nuked with good old rm -rf.

Mozilla's precompiled Rust for Fedora

It is still not easy to package rust for Fedora in the intended way, which includes using Fedora's llvm and libuv.

A much easier way which I now chose is to use the official rust binaries and wrap them in an rpm. This can then be build in Copr.

The rust-binary package includes the official release. The same method can also be used to create a rust-nightly-binary which could deliver the precompiled rust nightlies.

Now it's easy to enjoy rust on Fedora - especially with the lately discovered Rust By Example.

To get started you just need to run:

# We are using dnf's copr plugin, because it is - easy! $ pkcon install dnf dnf-plugins-core # Enable copr repo $ sudo dnf copr enable fabiand/rust-binary # Install rust-binary $ pkcon refresh $ pkcon install rust-binary $ rustc --version rustc 0.11.0 (aa1163b92de7717eb7c5eba002b4012e0574a7fe 2014-06-27 12:50:16 -0700)

Please note that the rpm only includes rustc and rustdoc, not cargo, rust's upcoming package manager.

yum, dnf - their common frontend: pkcon

pkcon - the commandline client for packagekit is actually quite nice.

# To search for a keyword $ pkcon search details opencl # To enable updates-testing $ pkcon repo-enable updates-testing # To install a package $ pkcon install -y clpeak # To see available commands: $ pkcon

What I like about it is, that it is fast. But maybe this is because of yum-cron.

Once PackageKit (and PackageKit-browser-plugin) is installed it also allows fancy things like this (you should see an in-browser field to install a package locally):

Package management using zif.

As yum was introduced I was happy about it's features. Also some of the later features like history and the rollback are nice and handy. But yum can be slow. If you want to use a different rpm high-level management system with a comparable featureset to yum give zif a try:

$ sudo yum install -y zif-tools PackageKit-zif

This also installs the zif backend for PackageKit - which appears to the user as the package update dialog. Many known commands will work:

$ zif search yum $ sudo zif install -y livecd-tools $ zif # will print help
