I've been hitting the same issue as well:

Is there any progress on remedying this issue?
It is frustrating having CI jobs continually fail because of this.

Asking yet again: what is the progress on getting this issue remedied?
We are continually having CI jobs fail because of this problem.

We are fully aware of the impact of the issue and are also experiencing CI jobs failures on our end. The fix (#296), which addresses this problem, is our top priority and is currently in the final review queue.

Are there any updates on getting this issue resolved?
It's been another week with seemingly no progress.
fix: prevent digest-mismatch on archive updates (canonical#296)
