I am using duplicacy-web to backup my Linux machine.
My prune and backup jobs have been failing with “missing chunks” errors. For example, for the prune job (arguments -keep 0:365 -keep 30:180 -keep 7:30 -keep 1:7 -a):
2025-10-09 14:03:36.258 ERROR DOWNLOAD_CHUNK Chunk 4be44dff3f6c0ab06d464acea0a4aa26f579c6e8d3308ea909f2e2087f551eb5 can't be found
Chunk 4be44dff3f6c0ab06d464acea0a4aa26f579c6e8d3308ea909f2e2087f551eb5 can't be found
For backup job:
2025-10-09 14:00:04.875 INFO BACKUP_START Last backup at revision 16987 found
2025-10-09 14:00:04.913 ERROR DOWNLOAD_CHUNK Chunk 4d126f60955c1fb9fe0d2ca9b41926e8c8663199d416ab0158cc32da4d8e5627 can't be found

I tried removing everything under the respective cache directories in ~/.duplicacy-web/repositories/localhost/*/.duplicacy/cache but that doesn’t really help since the errors are still there.
I checked, and these missing chunks don’t exist in the b2 bucket.
I have searched the forums etc., but I can’t find a solution to this problem. Currently, this is preventing me from backing up and pruning most of my data.
I’d appreciate any help.
