When I follow the guide on http://wiki.maemo.org/Py2deb I get the packages as it says there, and I can upload it to the repositories and download the package via apt-get, but how can I make a deb locally so I don't have to upload every small bugfix and flood the servers with crappy, even non-working builds?

extract the .tar.gz, CD into the directory that it makes, then:

r = p.generate(version,build,changelog=changeloginform ation,tar=True,dsc=True,changes=True,build=False,s rc=True)

Or change src= to Falso and build=True in the last line

Oh and one more thing, you can put non working builds (not on purpose of course) in -devel, users were already warned.

fatalsaint: Thing is, I don't have dpkg-buildpackage, and apt-get install dpkg-dev says that the package doesn't exist, but is referred to by another package (doesn't say which one..).

MohammadAG: seems as though that uses dpkg-buildpackage, it fails with py2debexception("buildpackage failed (see output)") where can I get that from?

You can't do it on the N900, you'll need a linux PC, just upload to -devel.
(actually you can do it, but I'm not spreading instructions on how to fill /)

Oh, that's a shame. Thanks anyway

Has to do with the SDK repo, if you want a hint
