Schema registry doesnt start doe to snappy compression error

What happened?

When I try to launch a container using ghcr.io/aiven-open/karapace:latest, I get an error.
Snippet of the error as follows:

karapace.schema_reader schema-reader ERROR Unexpected exception in schema reader loop

What did you expect to happen?

I expected schema registry to be up and running on my local on specified port.

What else do we need to know?

If I add the following
"libsnappy-dev" in Dockerfile line no. 38
"python-snappy==0.6.1" in requirements.in and requirements.txt
and build the image again locally and use the local copy of image, it works fine.
Schema registry in up and running on my local.

If this is a recommended fix, I can submit a PR.

Hey @tvainika , any idea when will the PR #773 be merged? I want to test this issue.

[avinashsingh77]

@matyaskuti I see develop tag was built after this issue was closed. When do we expect latest tag to have this fix?

@avinashsingh77 let me get back to you soon about the next release.

@avinashsingh77 I just published a new release, the latest image should contain the relevant fix now.
