OBS 2.10.x updates for Ubuntu 21.10

Hi, We released a number of updates for OBS 2.10 to support latest Ubuntu 21.10. It is using zstd for control file compression which required a number of changes. obs packages itself are not affected, but you will need to update build perl-BSSolv dpkg as provided by the OBS repository to be able to build for current Ubuntu. (Debian itself is not affected and even does not support zstd compressed control files either yet). There will also be a new osc release soon to support local builds as well. bye adrian -- Adrian Schroeter Build Infrastructure Project Manager SUSE Software Solutions Germany GmbH, Maxfeldstr. 5, 90409 Nuernberg, Germany (HRB 247165, AG München), Geschäftsführer: Felix Imendörffer
