Download the Netherlands language package from here: http://mirror.pnl.gov/ubuntu//pool/m...guage-pack-nl/
You should also add it to your sources.list: example: http://mirror.pnl.gov/ubuntu//pool/m...100421_all.deb
, or whatever the correct format is for your sources.list
Then, at the Ubuntu documentation wiki, there is this article on configuring language locales (https://help.ubuntu.com/community/LocaleConf
). You may need to install two packages: locales and localeconf.
The appropriate portion of the article reads:
First install the following packages: locales localeconf (see InstallingSoftware). (Package localeconf does not exist in neither gutsy nor intrepid)
When configuring the packages, you'll be asked a series of questions, but the most important are:
Select supported locales:
Select your language and its encoding. The encoding is how characters will be treated by the operating system. A good rule is to choose utf-8 locales.
For example, for my machine I chose: en_US.utf-8 and pt_PT.utf-8
Manage configuration with debconf:
Unless you're familiar with editing configuration files by hand, choose yes.
Default system locale:
If you prefer to have an English user interface, choose (like I did) en_US.utf-8, otherwise choose the language you selected during the supported locales configuration.
Settings to override:
This is where things get a little tricky. For example, I want my text to be "treated" with the Portuguese layout and also to use our national numeric and date formats, but the rest to be plain english, so I chose to override the LC_COLLATE, LC_CTYPE, LC_MONETARY, LC_NUMERIC and LC_DATE settings.
The following steps involve choosing the locale to apply to the settings you chose to override. In my system, I chose pt_PT.utf-8.
After the install system has finished setting up your locales, you're done. The next time you reboot your system, your new preferences will be applied. If you ever need to change this, execute the command:
$ sudo dpkg-reconfigure localeconf
The article is a bit dated, but it may still be useful to you.
