E: Package 'docker.io' has no installation candidate

[wenweiliang]

I was running the example provided by cwl_runner. It seems like docker.io can't be installed. Here is the error:

I don't believe there is anyone maintaining the cwl_runner example.
I think the right thing is to at least mark it as such in the README or take it down.

That said, I can make a few suggestions:

• Fix the docker installation issue in your copy of the script.

Docker installation has changed since this script was written. Instructions are on the docker web site, but the steps depend on the platform (Debian, Ubuntu, etc.) that you are using.

It might end up being a slippery slope of fixes to get it working. I'm just guessing since this file has not changed in a meaningful way since it was checked in over a year ago (Feb 2017).

• Use a different runner, such as Cromwell.

Cromwell documentation indicates that by Cromwell 30 it will support both WDL and CWL, although I don't see this called out in the release notes for Cromwell 30 or 31, and I have not yet tested it.

Hi @mbookman
Thanks for the suggestions. I have fixed the docker installation issue by changing docker.io to docker , but here is another error:

I don't see any CWL support in Cromwell documentation. In stead of waiting for Crowell updates, I am thinking to take a roundabout like installing rabix in VM to run cwl on google cloud. Anyways, please let me know if you have other thoughts.

@wenweiliang I too was looking at whether or not Cromwell supports CWL and although it was advertised as coming with release 30 (which was released in December of last year), I don't see it mentioned in the release notes or elsewhere in the documentation. I did come across this Rabix tutorial which seems to illustrate running Rabix on GCP using Funnel and TES, which might worth looking at.
