Yes, this is expected if you do not update your host configurations. Been there, ran into that, too, documented it in the package before doing the first upload of it. > I don't know if this iis fixable, but a notein README.Debian will > certainly help a lot. Ehm. That note is already in the package. But it's in /usr/share/doc/backuppc/NEWS.Debian.gz where it belongs. README.Debian is more for permanently relevant, debian-specific documentation. Citing from https://salsa.debian.org/debian/backuppc/-/blob/master/debian/NEWS#L12-34: If you want to keep you /etc/backuppc/config.pl file, make sure that you add at least this line: $Conf{RsyncBackupPCPath} = "/usr/libexec/backuppc-rsync/rsync_bpc"; Additionally you'll need to replace all occurrences of the no more existing $Conf{RsyncClientCmd} setting with $Conf{RsyncSshArgs} and possibly $Conf{RsyncClientPath} with accordingly updated values. Example: If you used $Conf{RsyncClientCmd} to configure the user with which BackupPC should login on the remote host and a remote nice level, replace $Conf{RsyncClientCmd} = '$sshPath -l root $host nice -n 10 $rsyncPath $argList+'; with those two lines like these in the client configuration file: $Conf{RsyncSshArgs} = ['-e', '$sshPath -l root']; $Conf{RsyncClientPath} = 'nice -n 10 /usr/bin/rsync'; See also "V3 migration" in the backuppc(8) man page or in /usr/share/doc/backuppc/BackupPC.html as well as https://github.com/backuppc/backuppc/issues/132. You'll even get that displayed during upgrade if you have apt-listchanges installed. Does this not suffice?
