Description

I checked that mdbook is in tool-cache, and it used to work serval days ago, but in these 2 days I get the error like the title.

Used environment

Environment: ubuntu-18.04
Version: 20201210.0
Included Software: https://github.com/actions/virtual-environments/blob/ubuntu18/20201210.0/images/linux/Ubuntu1804-README.md

Workflow code

here

Action output

here is the build. Related logs are in the Install mdbook section:

  Newest mdbook version available at crates.io: 0.4.5
  Downloading mdbook signature into /tmp/mdbook.zip.sig
  Warning: Unable to download mdbook == latest from the tool cache: Error: Unexpected HTTP response: 403

Expected behavior

Expecting to make use of cached mdbook like the old days.
