Wait, I tried them all at once and it worked fine.

What should I do now?

Install it as XP or 2000? Since I have both?

Already tried...no avail.

Anything on this?

dpkg - warning: ignoring request to remove ttf-oriya-fonts, only the config
 files of which are on the system.  Use --purge to remove them too.
brian@brian-laptop:~$ sudo dpkg -r ttf-oriya-fonts --purge

dpkg - warning: ignoring request to remove --purge which isn't installed.

^^ New response.

What to do when I cannot install dotnet20 or 30?

Please uninstall the Samyak/Oriya font, e.g. 'sudo dpkg -r ttf-oriya-fonts', then log out and log in again. That font causes strange crashes in .net programs.

^^^^ That's the message I get.
