Hi,
The machine I'm on runs Ubuntu-64-bit 10.04. Accordingly, I downloaded the brlcad_7.22.0-0_amd64.deb file.
I installed the package using dpkg -i brlcad_7.22.0-0_amd64.deb.
The output from dpkg seemed fine till this popped up :

"Processing triggers for shared-mime-info ...
Unknown media type in type 'all/all'

Unknown media type in type 'all/allfiles'

Unknown media type in type 'uri/mms'

Unknown media type in type 'uri/mmst'

Unknown media type in type 'uri/rtspt'

Unknown media type in type 'uri/rtspu'

Unknown media type in type 'fonts/package'

Unknown media type in type 'interface/x-winamp-skin'
"

brl-cad does not load. On opening archer, the logo (of Archer) is displayed for half a second, and then the windows automatically closes.
On running mged, I get a terminal opening, and again closing in less than a second.

Does the problem have to do with ubuntu 10.04? Are there any missing packages to install?

Thanks in advance.
