Actions reports no GitHub hosted runners available in matrix build

[johnae]

Describe the bug
For a day or two now all builds are failing (stalling really) with actions claiming there are no hosted runners available.

To Reproduce
Steps to reproduce the behavior:

1. Basically just run a matrix build in https://github.com/johnae/world

Expected behavior
All builds eventually run.

Runner Version and Platform

Github hosted runners.

OS of the machine running the runner? Linux

What's not working?

Several jobs just stall claiming no available runners. Since many jobs run to completion though, this seems odd. Especially odd that it happens every single build.

We are hitting this issue in https://github.com/haskell/haskell-language-server/actions since 17 hours. So 17 hours without any chance to merge code in our repo. Are there some workaround or way to check the status of runners availability?

The message is:

Can't find any online and idle self-hosted or hosted runner in the current repository, account/organization that matches the required labels: 'ubuntu-latest'
Waiting for a self-hosted or a hosted runner to pickup this job...

[jneira]

I've cancelled and reran selectively stalled jobs to see if they start to work again

EDIT: It seems that trick enables the builds

This seems to have resolved itself.
