♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or

• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

Resolving dependencies...

Could not find compatible versions

Because the current Bundler version (4.0.10) does not satisfy bundler ~> 1.0
  and Gemfile depends on bundler ~> 1.0,
  version solving has failed.

Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with `gem install bundler:1.17.3` and rerun
bundler using `bundler _1.17.3_ lock --update rspec`
