My First Major Disappointment in Fedora (Updated)

ABOUT three weeks ago I decided to go back to working with Fedora. This distribution served me well over the years, especially in distributed clusters. Fedora 14 looked very promising and it still is, but there are creases that are hard to undo and to hide. In order for matters to improve I will post a quick rant and hope that someone, somewhere will help address the issue that I’ve already reported (I also submit bug reports whenever that’s possible).

My main problem is package specific. The problem was first mentioned here. Thanks to a blog comment from Rahul I was made aware of fairly trustworthy repositories where packagers offer alternative packages. I soon found this newer build of Octave (needed to manually uninstall the existing one as it does not support updating existing packages). It is one of those unsigned packages, which require the user to jump through some hoops. The changelog looked promising because the latest entry mentioned exactly the bug that I was suffering from (many other people must be suffering from it too):

* Sun Feb 28 2010 Alex Lancaster <alexlan[AT]fedoraproject org> – 6:3.2.4-3
- Temporarily disable %check to enable build to complete and ensure upgrade path works. This works around a crash in the imread.m image test script, this may be the same problem as described by upstream here:

So, here goes:

This can be done from the GUI as well. But it’s not working. The bug still exists and prevails after the new package gets installed. To make matters worse, for some reason, yum just disallows installing unsigned packages. It does not even produce a warning with an opt-out/force option. It’s very stubborn, so I had to use the GUI. Then, running the program (the new build) showed that:

octave:4> imshow('Konqueror.jpg')

Oh, wonderful. Well, eventually I found a way to run qtoctave again. Checking the version/build names again:

Yes, even octave-3.2.4-3.el6.i686 has this same bug, so what gives? In Kubuntu 10.04 there is no such problem, not in the packaged version of Octave. Having to go through less official routes to unsigned packages is daunting enough for most people; finding out that it still does not work is even a lot worse. The problem here is not really Fedora but lack of coordination between octave and the magick folks. qtoctave handles this admirably well by restarting octave and not just letting the entire program crash. But still, having wasted several hours on this first looking for bugs in my code and then playing with packages rather than doing research (realising that my code was not the problem), I am left a bit bitter about my Fedora 14 experience. It is not as though I have been too lazy trying to resolve this and for the time being it seems like I will do more of my work on my Kubuntu box. It happens to have done packaging of Octave more successfully (at least that older version).

Update: not even stepping back to older versions of ImageMagic has worked and yum had the same limitations because the packages were unsigned.

I’m giving up. Maybe I just need to go to far older versions for compatibility, but I tried the oldest ones built for Fedora 14.

  1. twitter Says:

    It’s hard to beat Debian package management. Sometimes you might need an “old libs” package for compatibility.

    If you need to run old versions of software, why don’t you do it in a VM with a stable version that used to run it?

  2. Roy Schestowitz Says:

    That’s why I do it with Kubuntu for the time being.
