Using dch to increment release number without a suffix?

Solution 1:

To release 1.0.0-2 you need to use the -U option, see dch man page:

   --upstream, -U
          Don't append distro-name1 to the version on a derived          
          distribution. Increment the Debian version.

Initial debian/changelog:

foo (1.0.0-1) trusty; urgency=medium

  * Initial release

After dch -U:

foo (1.0.0-2) UNRELEASED; urgency=medium

  *

foo (1.0.0-1) trusty; urgency=medium

  * Initial release
