The problem is that : we have started to work with Dulicity long time ago in a dedicated server for backups, we have changed our backup server some months ago with a local one (in our building) but our developper forgot to save the private key from the first backup server, this key stayed in the first backup server which has been erased by the hoster... Now we have the backup files, the public key and the password but no way to provide the private key to Duplicity.

hey Tim,

unfortunately supposing you encrypted against one public key only and
managed to rid yourself of possession of the matching private key you
lost the possibility to decrypt. not that it helps you now, but in case
you consider duplicity or key encryption in general - it is possible to
encrypt against several public keys at the same time, making it possible
for each of the matching private keys to decrypt later. if you add
public keys of several persons, the likelyhood of losing the keys get's
much lower.

good luck.. ede/duply.net
