tails-iuk-generate-upgrade-description-files fails without any --previous_version
Following the release process for a first Tails X.0 pre-release that gets security support (typically X.0~betaN or X.0~rc1) with empty $IUK_SOURCE_VERSIONS
leads to the tails-iuk-generate-upgrade-description-files
command failing due to no --previous_version
argument. In that situation tails-iuk-generate-upgrade-description-files
should not fail but happily create "empty" UDFs for --version
and all --next_version
:s.
