#
# This workflow builds the source package for Keyman for Linux, and then builds
# the binary packages for the released versions of Ubuntu. It also signs the
# packages. Released Keyman versions get uploaded to the LLSO repository.
# It is triggered by a repository_dispatch event with the
# types `deb-release-packaging:*` and `deb-pr-packaging:*`.
#
# We use the filename `deb-packaging.yml` even though we only do Ubuntu
# packaging here, because we're packaging the .deb format, and because it's shorter.
