How to reproduce it

Happens sometimes.

Expected behaviour

Even if not a good practice, we might want to just skip the current distro if any exception happens, in the crawl_kernels loop.
We can have multiple type of exceptions:

  • requests.get() generated
  • raise_for_status() generated
  • plus many more

And i don't think we want to deal with every of them.
