I am creating a deb package for an opensource project I have started called WideMargin

When I try and install my deb package in 10.10 using the Ubuntu Software Center I get the following text on screen.

Sorry, 'widemargin' is not available for this type of computer (i386).

Despite this message it still installs and works fine.

In my control file I have the following line:

Architecture: all

I assumed this would allow it to work on all architectures.

What am I doing wrong?

As this is an open source project please feel free to poke around in my package source and tell me whats wrong.

I ran the following command as requested:

dpkg-deb --control widemargin_1.0.0_all.deb

And it produced the following results:

Package: widemargin
Version: 1.0.0
Architecture: all
Maintainer: Daniel Hughes <>
Installed-Size: 4744
Depends: mono-runtime (>= 2.6.7), libgtk2.0-cil (>= 2.12.10), libmono-sqlite2.0-cil (>= 2.6.7)
Section: unknown
Priority: extra
Description: Quick and simple bible software.
 Bible software with a focus on speed and usability.

Software Center is nowadays very picky. Try installing with dpgk. – Takkat May 14 '11 at 8:44
there is no message with dpgk – trampster May 14 '11 at 8:45
@Takkat I am expecting my users to use the software center, So I need to fix the package, not find a work around for installing – trampster May 14 '11 at 8:47
Can you add the output of dpkg-deb --control your_package.deb to your question? – Lekensteyn May 14 '11 at 9:01
@lekensteyn that command produces no output.... – trampster May 14 '11 at 9:16

My computer is an i386 which is what most computers are. I'm not sure of all the options here, but on my computer the line:

Architecture: all

Should be changed to:

Architecture: i386

The program is written in c# and uses mono, it is architecture independent. So it will work on all architectures. As such it does not need to be built for each architecture. – trampster May 15 '11 at 2:59
