Unable to 'check' using a different version of duplicacy web UI

Support
#1

A source was backed up using version 1.6.3 to a MinIO S3 endpoint storage. Everything appears to work well. We can backup additional files, check, and prune.

We then connect another Duplicacy 1.7.2 instance to the same storage. We are using the correct storage password. This new instance seems to restore without issue. However when we attempt to run a ‘check’ from the new instance we receive the following error:

ERROR DOWNLOAD_DECRYPT Failed to decrypt the file snapshots/stagingbackup/314: The storage doesn't seem to be encrypted
Failed to decrypt the file snapshots/stagingbackup/314: The storage doesn't seem to be encrypted

I suspect that this file snapshots/stagingbackup/314 became corrupted on the storage, but the computer running 1.6.3 still has a correct copy of this file in the cache.

To confirm, rename the cache directory (~/.duplicacy-web/repositories/localhost/n/.duplicacy/cache where n is the index of the backup) and specifically check the revision 314 (add a -r 314 option to a check job). Don’t just delete the cache directory as it may be usefully if you want to recover revision 314.

Thank you for the correct pointer @gchen. The snapshot was corrupt and everything is now working as expected.
