I've successfully created a package and uploaded it to mentors.debian.net - but it disappeared, having checked the FAQ, I assume I must have uploaded a binary package so I need to upload a source package.
My directory has
<myapp>.dsc
<myapp>.tar.xz
<myapp>.build
<myapp>.buildinfo
<myapp>.changes
<myapp>.deb
<myapp>.mentors.upload
So it looks like I've got all the possible files I might need. The command is dput
<myapp>.changes which doesn't specify source/binary, so how do I ensure that dput uploads the source package?
