How to remove Mono from Ubuntu 10.04 Lucid Lynx [Updated]

Monogenea

Monogenea

Monogeneans are ectoparasites, meaning they live on the surface of their host’s body (as opposed to inside of it) and feed mainly on mucus and other detritus. To ensure they do not lose grip of their host, Monogeneans have very highly developed attachment appendages such as suction devices, pincers, hooks or spines. Most species require only one host to complete their life cycle and they are mostly hermaphroditic. Monogeneans are a type of Platyhelminthe (flatworm) and as such have only one “opening” where food is ingested and any waste is expelled.
OK, that’s enough of a biology lesson. If you are reading this then you probably know why you are here already.

To remove Mono from your shiny new desktop installation of Ubuntu 10.04 Lucid Lynx enter the following command (after taking the usual precautions like backups of your data etc):

sudo apt-get purge libmono* libgdiplus cli-common libglitz-glx1 libglitz1

[UPDATE: Many thanks to Directhex who pointed out my error regarding the need to remove libsqlite0. I’ve removed it from the command above. He also requested (you can see in his comment below), that I mention that the mononono package is no longer particularly effective at preventing Mono from being installed. Thanks for the prompt Jo, I was going to but I just forgot.]

This is almost the same one as used for the Karmic Koala release (9.10), and for me the result of the above command was as follows:

The following packages will be REMOVED
cli-common* f-spot* gbrainy* libart2.0-cil* libflickrnet2.2-cil* libgconf2.0-cil* libgdiplus* libglade2.0-cil* libglib2.0-cil* libglitz-glx1* libglitz1* libgmime2.4-cil* libgnome-keyring1.0-cil* libgnome-vfs2.0-cil*

Do you want to continue [Y/n]?

I chose to accept this and proceeded. Of course YMMV so please check carefully before hitting that enter key. The purge switch of this command removes any configuration files as well as the packages themselves.

Compared to Ubuntu 9.10, in 10.04 there appears to be just one new Mono dependant application called gbrainy (in the Games menu) which is described thus: “a platform to train memory, arithmetical and logical capabilities with many sorts of different exercises of different difficulty levels”.

Unfortunately it appears as though the “training” objective of gbrainy might not be realised…

Over the last year or so, the BBC have carried out an experiment which examined “brain trainer” games. Subsequent analysis of the data found that these brain trainers are an empty promise as reported here in The Guardian:

Practising brain-training games will improve your performance on brain-training games, but that effect will not transfer to other aspects of brain function. They will not make you brainier, so you may as well just pootle around on the internet.

It seems that not much grey matter will be lost by removing the gbrainy package then 😉

Gnote and Getting Things Gnome

Gnote and Getting Things Gnome

The other applications expunged by removing Mono from the default Desktop installation are the same as last year: F-Spot and Tomboy.

For a very similar alternative to Tomboy try Gnote, and as I like task-related management too I also recommend the excellent GTG [Getting Things Gnome] application. To install these two simply type: sudo apt-get install gnote gtg.

The alternative for F-Spot I usually use is a combination of gthumb and Gimp, the latter of which has been removed from the default Lucid desktop install to make space for other things. Both of these applications can be easily installed by a simple sudo apt-get install gthumb gimp command. However there is now a new kid on the block which looks quite exciting called shotwell. Shotwell will be the default camera/image app in the forthcoming Fedora 13 distribution replacing gthumb (as it has no dependencies on Mono in the default desktop installation). It is also, I was pleased to discover, available in the main Lucid repository so can be installed using either the command line: sudo apt-get install shotwell or you can use the very easy and graphically attractive Ubuntu Software Centre (as you can for the other applications listed above also). This is how Fedora describe Shotwell in the preliminary release notes:

Shotwell is an open source photo organizer designed for the GNOME desktop environment and has replaced Gthumb by default in Fedora 13. It supports the following features:

  • import photos from any digital camera supported by gPhoto
  • automatically organize events containing photos taken at the same time
  • use tags to organize your photo collection
  • edit non-destructively when altering photos, without ruining originals or using disk space for each copy
  • publish photos to Facebook, Flickr or Picasa
  • one-click auto-enhancement
  • rotate, mirror, and crop photos
  • reduce red-eye and adjust the exposure, saturation, tint, and temperature of your photos
  • edit any photo, even if it’s not imported to the Shotwell library

I haven’t used Shotwell yet but it sounds like a good one to try out.

There you have it and hopefully that will be it for another 6 months on this subject.

How to remove Mono from Ubuntu 9.04 Jaunty Jackalope [Updated]

SABDFL groks Mono

It’s that time again 😉

Fortunately, Mono is still quite trivial to remove and has not, apparently, increased its infiltration of the Ubuntu/Gnome code base as one might have been led to believe if you’d read this on the 1st April:

“Mark Shuttleworth, the Benevolent Dictator for Life of the popular Ubuntu Linux distro, has announced his plans to rewrite all of Gnome, X11 and the Linux kernel using the Mono platform…

Ubuntu is Linux for human beings, and, believe it or not, Microsoft employees are human beings too. We think we need to work closer with Microsoft to ensure heterogenous data silo paradigm middleware enhancements can continue to grow. Oh, and they gave me this nice T-shirt.”

As was the case with 8.10 Intrepid Ibex, there are just two applications in the default Jaunty desktop install which depend on Mono: F-Spot and Tomboy.

As an alternative to F-Spot, I happily use the Gnome viewer gThumb for managing the import and deletion of images from our digital cameras. I actually think it is better for a simple reason. It allows me to copy the images off my camera and delete them from the camera at the same time. The last time I tried F-Spot (admittedly quite a while ago now) I could never find a setting to do this.

And for note taking I have been happily using notecase. Although I note [pun intended] that the developer has stopped work on the free version himself the code is available under a BSD license so if anyone wants to pick it up and run with it they can. Anyway – notecase works fine for me and is still in the repos.

There are many other note taking type applications too. Here is what looks to be quite a comprehensive (albeit old) list of them: http://linuxappfinder.com/utilities/notes

But this is just GREAT!

Gnote: Tomboy minus Mono
Whilst I was preparing this article, I came across this on April 1st too. I actually did think it was a joke.

However it seems not; a bored and unemployed (ex Novell/Suse) developer, Hubert Figuière, is porting [has ported] Tomboy to C++ and calls it Gnote.

You can now use a virtually identical application to Tomboy without Mono! (This is still an early development so YMMV).

There is a PPA for Ubuntu here very kindly organised by Vadim Peretokin. I installed it on my intrepid desktop just to see it and it looks exactly the same as Tomboy!

Even better, as it isn’t built on top of Mono, it has fairly meagre requirements too:

sudo apt-get install gnote
[sudo] password for alord:

3.4MB vs. 54.0MB. That’s a decent comparison I think.

OK. The moment you’ve all been waiting for…

To remove that patent-trap-masquerading-as-free-software from your Shiny New Ubuntu Jaunty system simply type:

sudo apt-get purge libmono0 mono-common libgdiplus

[UPDATE]
Thanks to a keen eyed commenter, Lupine, we note that there is another package that lurks hidden and must be explicitly removed. I have added libgdiplus to this command since first publishing. To remove it individually just enter sudo apt-get purge libgdiplus. Thanks Lupine.
[/UPDATE]

Then watch what happens next…

Oh yes please…

To wrap up this post, we’ve been using Jaunty on various devices for some time now. It’s been really stable, boots very fast and is probably the best desktop operating system you can get anywhere and for any price right now. Thanks to Canonical and the rest of the amazing FOSS Community for making Ubuntu and this release happen.

Our Libertus Server Appliances, with the Mono-free Jaunty 9.04 server edition, are available from today.
