Package: gmp-ecm
Version: 6.4.2-1
Severity: important
Justification: policy ยง7.4 "Conflicts should be used unless ..."
Tags: patch
Hi,
gmp-ecm conflicts with ecm because historically they both provided
"ecm" commands (bug#580548). Now that cmdpack ecm has been renamed to
ecm-compress, gmp-ecm and ecm are coinstallable and the conflict can
be made versioned.
Policy explains:
| However, normally the presence of an "earlier than" version clause
| is a sign that Breaks should have been used instead. An "earlier
| than" version clause in Conflicts prevents dpkg from upgrading or
| installing the package which declares such a conflict until the
| upgrade or removal of the conflicted-with package has been
| completed, which is a strong restriction.
so the patch below switches to a Breaks+Replaces. Seems to work ok.
Thoughts?
Jonathan
