Question

I'm trying to run a project which has Spring-Boot, Google Cloud Pub/Sub with subscriber implementation, its giving following error

I was able to run this project but something has changed and now I can't run it on Linux Fedora 30 machine but on Windows its running fine, I have looked what might trigger this but they say I have different versions of grpc-netty and grpc-netty-shaded, but they are the same 1.21.0.

Also, I'm only using the google-cloud-pubsub-client and have no control on its version. Do I need to install as package locally as well? I found some for grpc and netty in RPM.

Any help is appreciated, if you need anything else please comment.

Thanks

Since nobody had answer my question, I will put it for future reference.

As I was on Fedora 30, it was missing a library libxcrypt-compat, after installing it, build ran successfully.
