Debian/Ubuntu Support in Spacewalk 2.7

Significant improvements to Debian/Ubuntu version parsing and matching were made in the Spacewalk 2.7 release. The majority of the changes were done in Spacewalk server. However, there is a change that must be applied to client systems as well. When upgrading from a previous Spacewalk release to Spacewalk 2.7, it is also required that all Debian/Ubuntu channels be cleaned and synced again to import the right versions

There are still a few rough edges that need some development attention:

  • The current version comparison logic does not distinguish a dot (".") from a hyphen ("-"), a tilde ("~") or a plus ("+") character. This leads to some packages wrongly shown as an update for a client in Spacewalk when the package is actually a downgrade. The client, however, uses a correct comparison and handles the package upgrade correctly.
  • The "deb" importer does not import all the package header information into the database and the repository-writer will not write the missing information to the repository metadata served by Spacewalk. This will lead to problems on the client in case of the missing Multi-Arch header: Clients will try to reinstall the same package over and over again when this header is missing.
  • A "deb" repository provided by Spacewalk is not GPG-signed and thus will not work without disabling secure-apt. Spacewalk imports and recreates the repository based on the imported package catalogue, this will destroy the GPG-signing of the repository vendor.

Required Client Update

The client needs to be fixed also to report an "X" instead of an "0" as the release if it is empty.

The file /usr/share/rhn/up2date_client/debUtils.py needs the following change:

Clean, Then Sync Channels After Upgrading To Spacewalk 2.7

Spacewalk 2.7 changes the parsing to handle the Debian package version components according to definitions from here. After an update to Spacewalk 2.7 the existing Debian/Ubuntu channels must be cleaned and synced again to import the right versions.
