Rspamd is upgraded to 2.0 which deprecates the SQLite Bayes backend. We then moved to the Redis backend (the default since Rspamd 2.0). If you don't want to relearn the Redis backend from the scratch, we could manually run
rspamadm statconvert --spam-db /var/lib/rspamd/bayes.spam.sqlite --ham-db /var/lib/rspamd/bayes.ham.sqlite -h 127.0.0.1:6379 --symbol-ham BAYES_HAM --symbol-spam BAYES_SPAMSee the Rspamd migration notes and this SNM Merge Request for details.
