Fedora Rules

There is a selinux issues in Yum Extender 2.9.x in Fedora 12 (Beta) and F11.

It will give problems when installing new kernels

you will get messages like this

13:33:46 : YUM: /sbin/new-kernel-pkg: line 292: /sbin/depmod: Permission denied
13:34:05 : YUM: /usr/bin/ldd: line 118: /sbin/udevd: Permission denied

It is caused by /usr/share/yumex/yumex-yum-backend is not labeled correctly.

Run the following commands as root to fix it.

chcon system_u:object_r:rpm_exec_t:s0  /usr/share/yumex/yumex-yum-backend
restorecon -r /usr/share/yumex

I have requested it to be added to standard SELinux policy in Fedora.

https://bugzilla.redhat.com/show_bug.cgi?id=527528

To fix an already installed kernel in F12.

$ rpm -q kernel-PAE --scripts | grep -e '--install'
/sbin/new-kernel-pkg --package kernel-PAE --mkinitrd --dracut --depmod .......

copy the /sbin/new-kernel-pkg command and run it as root.

/sbin/new-kernel-pkg --package kernel-PAE --mkinitrd --dracut --depmod .......

if you are using a non PAE system then substitute ‘kernel-PAE’ with ‘kernel’ in the rpm -q command.

yum in Fedora 12 Beta contain a new cool history feature that make it posible to
see what happed in part transaction and redo/undo past transaction.

Example 1: Showing the past transaction

The have been some discussions on the fedora-devel list on the latest Thunderbird 3 Beta 4 release, because it introduce some new features there make things look and feel different.  It looks like there is 2 kind of opinions.

a). This kind of changes should never enter a stable release of fedora as an update.

b).  Let me have the latest and greatest as long as my system don’t blow up.

I feel most for b), if I was feeling for a),  I would use RHEL/Centos, instead of Fedora.

One of the reasons I use Fedora, is because it evolves over time, not only between releases, but many of the applications also evolves on the current release and of cause we can’t change the low level parts of the system on the current release and use too unstable components, because it will make peoples systems blow up and we don’t want that. But that don’t mean that we can’t evolve and discover new grounds.

If you don’t like some changes in a application like thunderbird, then don’t beat up the maintainer, take it upstream. It is one of Fedora values to follow upstream and if upstream make a change like disable ‘Ctrl-Alt-Backspace’ in X, then Fedora will follow. You can always enable it on your system, if you like an easy way to kill your GUI in a moment of anger.

One of the great things about Fedora and Linux is you have a lot of choices and if you don’t like something, then turn it off or use some other applications there better fits you needs.

I have made a new preview release of Yum Exender NextGen

Get Fedora 11 packages here:

http://timlau.fedorapeople.org/files/yumex/

The mayor change is that the gui is now running as normal user and only the backend doing the yum magic is running as root, so you will see a consolehelper root password prompt, just after the gui is shown. I know that consolehelper is a yesterday thing, but there is no easy to use replacement yet.

I have been working hard on beating Yum Extender NextGen into shape and I really like the result so far.
I have made a new screencast showing the the latest preview release 2.9.0-0.8.

If you what to try it out, then read more here

It will only work in Fedora 11, because I use a lot of latest and greatest Gtk stuff.

I was working on my desktop and this pops up.

Maybe I’m old, but not that old and I can’t read Persian.

(I know it is supposed to be a new feature in F11, but this is going to confuse a lot of people)

I have created a new Yum Extender homepage based on WordPress. It is a much easier to maintain and better looking than the old one.

Article about Yum in Linux Magazine

Some of it is a little outdated, but still nice

I have made a preview release of the next version of Yum Extender.

It is not complete yet, but i am getting closer

You can find some rpms here:

But remember this is a very early release, so dont expect it to be rock solid yet.

EDIT: Fedora 11 RPM’s added too (Working with Presto now )

I have for a while been working on creating the future version of Yum Extender, most of the code is rewritten from scratch.

Here is a little screencast of the current look.

The look might change in the future
