[Duplicity-talk] Can't delete duplicity s3/glacier archives?

[Henry S. Thompson]

For backing up my system to s3, I'm running:

 - duplicity 0.8.17
 - Python 3.9.2
 - boto3 '1.24.36'

My daily backups run fine.  As desired they are moved from s3 to
glacier after a month, duplicity status shows everything as it should,
with monthly full backups and daily incrementals, going back 62
months, e.g.

  Secondary chain 54 of 62:
  -------------------------
  Chain start time: Sun Oct 24 02:05:01 2021
  Chain end time: Tue Nov 23 02:05:01 2021
  Number of contained backup sets: 31
  Total number of contained volumes: 8223
   Type of backup set:                            Time:   Number of volumes:
                  Full         Sun Oct 24 02:05:01 2021              6450
           Incremental         Mon Oct 25 02:05:02 2021                64
                 ...[30 more incrementals]...

But when I try to prune old incrementals

  duplicity remove-all-inc-of-but-n-full 7 --force boto3+s3:///[bucket name]/

I get

  Local and Remote metadata are synchronized, no sync needed.
  Last full backup date: none
  No old backup sets found, nothing deleted.

I've searched and found nothing.

Is the problem perhaps because the older archives are on glacier? The
metadata is all on s3 as it should be...
