When publishing a GitHub page for a repo, the deploy action might fail with an HTTP-400 error:
Failed to create deployment (status: 400) with build version <build version hash>.
Responded with: Deployment request failed for <build version hash> due to in progress deployment.
Please cancel <deployment hash> first or wait for it to complete.
Based on a (now apparently defunct) community discussion thread. Another (still working) discussion of the same issue.
List deployments for the repo:
curl -u "<username>:<password or API key>" -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/<username>/<reponame>/deploymentsFind the one that where the attribute sha matches the <deployment hash> mentioned in the deploy action's error message.
Make a (mental) note of the
urlattribute of that deployment (needed in step 3).
check the status of the deployment by opening the statuses_url, there's probably an "in progress" entry
delete the offending deployment:
curl -u "<username>:<password or API key>" -H "Accept: application/vnd.github.v3+json" -X DELETE <deployment URL>maybe wait a minute or two, then re-start the "pages build and deployment" workflow
-
according to a comment by @easrng, you might also need to cancel the pages deployment:
curl -u "<username>:<password or API key>" -H "Accept: application/vnd.github.v3+json" -X POST https://api.github.com/repos/<username>/<reponame>/pages/deployments/<deployment hash>/cancel

for more info regarding the relevant ReST API endpoints, see the GitHub API documentation, e.g. regarding Deployments and Pages.

for API authentication, instead of the
... -u "<username>:<password or API key>" ...part, it is also possible to use... -H "Authorization: Bearer <access token>" ..., using an access token with the required permissions (see API docs for required permissions). This is also the way shown in the examples in the API docs
I also had to do this:
