If you don't want to fill the computer up with i386 libs that you don't need.

There are two sets of packages for MongoDB; the standard Ubuntu packages, and a set published by 10gen themselves. The standard packages are out of date, especially for older releases of Ubuntu, so it is probably a good idea to set yourself up to install from the 10gen repositories. The error message you quote suggests that you might have already tried ...

The message "no such file or directory" is displayed because there is a missing shared library.

This is a deliberate change in behaviour (source): As of Ubuntu 11.10, update-manager no longer prompts for the user's password to apply updates. This was decided to improve usability and to make it easier for users to apply security updates and therefore increase system security. The rationale is as follows: Like in previous releases, by ...

I found a hint to the solution in Ubuntu Forums, where a user sent a link to Gnome Developer Center explaining the configuration for Gnome Shell. My solution explains what to do for Unity. You will need to install dconf-tools if you don't have it yet: sudo apt-get install dconf-tools Then run the tool (for example, pressing Ctrl+F2, then typing ...

Gnome has not been removed from 11.10. Unity in 11.04 is based on Gnome2, and in 11.10, on Gnome3. The Gnome you are familiar with (aka Gnome2) is no longer supported by the Gnome Foundation - the decision that has nothing to do with Unity. If you want to try Gnome3's default shell, install the gnome-shell package. If you wish to keep using Gnome2, your ...

I was having the same problem on my Acer Aspire 3000 laptop, getting the magenta blank screen. Here's what worked for me.

You use a lens to look at the data returned by a scope. For instance, you have one single music lens, which uses different scopes to display its results: local music, music in the Ubuntu One Music Store, music from the Amazon MP3 Store, etc. The main idea is that there can be lots of different, but very similar, data providers. The scope is used to make ...

If you hold down Alt the Suspend option becomes "Power Off". Edit: Although I should add that I use gnome-shell and I prefer to use an extension to add the power off option to the menu without having to hold alt.

It appears to be a joke. According to Wikipedia's article on aptitude, apt-get contains an easter egg resembling cowsay that can be found by issuing the moo command: $ apt-get moo (__) (oo) /------\/ / | || * /\---/\ ~~ ~~ ...."Have you mooed today?"...
