  • End of life for Ubuntu versions

    In the story relating to release upgrades for Ubuntu, below the end-of-life table for the Ubutu Releases from the Ubuntu Wiki – just to have it all in one place; I’m only including the LTS (long-term support) editions, as these should be the only ones deployed on live production systems. In the meantime, Maverick Meerkat is due in October 2010, supported for 2 years. (more…)

  • [SOLVED] phpSysInfo – failed to open stream on Ubuntu 10.04?

    phpsysinfo eval : 2 Message : parse_ini_file(/usr/share/phpsysinfo/data/distros.ini): failed to open stream: No such file or directory File

    There is a simple fix for this in version 3.0.5:

  • Maverick Meerkat Alpha 1 (Ubuntu 10.10) is out

    Quick note – Ubuntu 10.10 – Maverick Meerkat is out. Mark Shuttleworth had already given a vision for it back in April 2010.

    Let the “light”ning commence! 🙂

    “Maverick Meerkat” is the code name for Ubuntu 10.10, scheduled for release on 10 October 2010. See the Maverick release schedule. A quick sketch-up roadmap is over here.

  • Upgrade your Ubuntu Distro from the Command Line – Server or Desktop

    What release / version are you running?

    cat /etc/lsb-release

    or

    cat /etc/issue

    But you knew that already — to upgrade the version of the Ubuntu installation you have is quite simple – just storing it so that I have it somewhere 🙂 (more…)

  • Ubuntu Lucid Lynx (10.04) LTS is out

    They’ve passed their RC status and have moved into full Long-Term Release for Ubuntu Lucid Lynx — local mirrors are still showing the RC version, but it’s out!

    What’s new?

    • F-Spot replaces the GIMP
    • PiTiVi video editor added
    • GNOME 2.30
    • New themes: Ambiance and Radiance
    • New wallpaper
    • Linux kernel 2.6.32
    • New nVidia hardware driver
    • Gwibber social media application
    • Faster boot time, with a different look and feel on the bootsplash screen
    • Ubuntu One adds contacts and bookmark sharing
    • Ubuntu One music store integrated into Ryhthmbox
    • Ubuntu Software Center 2.0

    I’ve only played with the 10.04 Server edition so far, and the faster boot time is definately a big win (though some regressive network driver support still needed to be ironed out – hopefully sorted for the final release…)

    Yay!!! Well done, guys!! Thanks for a new, even more sparkly LTS!

  • KnowledgeTree 3.7.0.2 Document Indexing and Indexer issues (SOLVED)

    Argh. Well, it’s really not quite out of the box, at least on Ubutu Server 9.10 (after reinstallations required after initial failures…), so this is just a selection of the fixes that made the import and indexing of the 160 000 files at 102GB possible. So for KnowledgeTree 3.7.0.2 Commercial Edition (the same holds true for the Community Edition), the following should help:

    1. Use the best-practice advice when doing the local file system import – rather do 10 000 files at a time rather than 100 000 at once. Really. Trust me. It defeats the whole idea of just running a batch job. Completely. As you’d expect the option of saying – just transfer all data in directory X. But alas, that doesn’t work. So do it in batches. Manually.
    2. Tika Apache Indexer for Lucene – not so much on PDFs, Docs, XLS or PPT files. Install catdoc (which includes catppt and xls2csv) and pdftotext (which you’ll find in xpdf-utils).
      1. apt-get install catdoc pdftotext
      2. modify knowledgetree/search2/indexing/extractors/TikaApacheExtractor.inc.php and comment out the mime types that are affected above from the returned array in getSupportedMimeTypes() – PDF, XLS, DOC and PPT: (more…)

  • KnowledgeTree 3.7.0.2 reinstallation site startup failure (SOLVED)

    OpenOffice.org startup failures, indexing issues and other niggles forced me to re-install KnowledgeTree 3.7.0.2 Commercial Edition (the same holds true for the Community Edition) more than once during setup. I was met with this delicious error notification which killed all further activity on the site (and prevented the startup of /setup/wizard/, control.php, browse.php, login.php — well, everything, really):

  • Ubuntu 10.04 LTS now in beta

    Ubuntu 10.04 LTS (beta) now out…

    Ubuntu 10.04 went beta yesterday afternoon, with downloads at http://releases.ubuntu.com/10.04/, otherwise from the download mirrors.  Lucid Lynx, as it’s called, enjoys LTS support (ie 5 years out the box).

    This version promises as a better (and faster) boot experience, new themes, version 2.6.32 as the Linux kernel, Firefox as default browser — with default browser page changed to Yahoo! (that’s new!) nVidia hardware support using open source drivers has improved, and a whack of new features for the Ubuntu Enterprise Cloud have been included. (more…)

  • New ClamAV / clamscan / freshclam on old Ubuntu (Feisty or the like)

    A typical situation – you get to audit a server setup which hasn’t seen a apt-get update / apt-get upgrade or even apt-get dist-upgrade since Netbooks were a pipedream.

    “Please don’t change anything, we only want a virus scanner, but the update cache is busted,” they say. That you see a whole bunch of 404‘s in the apt (or aptitude) feedback is normal — there is no active repo for this flavour anymore! Long-gone!

    So – what to do? As you would, you compile from source. Ha — one gotcha — zlib‘s probably not installed (compression library, as you know).

    So – quick move to virus scanning happiness (on the latest version):
