Barman-cloud requires lz4 and snappy compression libraries for backup and WAL compression. The pythonbuilder stage needs the development headers (liblz4-dev, libsnappy-dev) to compile the Python C-extensions into wheels, and the final runtime image needs the shared libraries (liblz4-1, libsnappy1v5) for the extensions to function. Without these dependencies, backups fail when attempting to compress data, causing the backup to enter a failed state. Signed-off-by: Marco Nenciarini <marco.nenciarini@enterprisedb.com>
