Hello,
I have an old S3QL filesystem that has been untouched since 04/2014. I am
using the S3QL version 2.26 that comes with Ubuntu 18.04. Mounting the file
system fails with message "s3ql.backends.common.CorruptedObjectError:
Invalid metadata format: pickle".
I have tried using the upgrade command but get the same message:
> s3qladm upgrade s3c://objects-us-east-1.dream.io/chrevesdata/S3QL/
> ERROR: Uncaught top-level exception:
> Traceback (most recent call last):

I see from past questions that you have suggested installing old versions
<https://groups.google.com/d/msg/s3ql/mYVW_86roC4/RE_peanEAgAJ> and
upgrading the file system one by one. As this is quite difficult to satisfy
the software dependecies and even to get some of the old S3QL versions is
this still the proper method? Am I doing something else wrong?
Thank you!
