Gentle bump: this is breaking CI for Hylo.

I am no expert on the tech underlying this plugin, but to my layman's eye it looks like we are failing here trying to import non-existent GPG data. Which we are trying to download here. It strikes me that the download could fail and I don't see any code to detect that case. I note that this plugin never fails on MacOS, but then it also never has to download these GPG keys.

[dabrahams]

At least one alternative plugin fails in exactly the same way. Not sure what it means yet. I've never failed to get the keys file myself (so far)…

So far, this alternative swift-installation action doesn't seem to be causing these spurious failures. Another workaround I know of is to use a dev container in which you've pre-installed swift, making this step unnecessary.

This is also breaking CI for Teco Core, which uses a merge queue that doesn’t allow manually retrying failed tests.

I decided to work around by disabling merge queue temporarily, but I hope this can be resolved ASAP🙏

Oh wow, thanks for the tip! I am already using a devcontainer on one of my repositories that is running into this issue, never considered to reuse it in CI as well.
