I guess this is a case where we use "master" of the example and the prereqs no longer fit our stack.

The quick fix is to find an older commit where the build still works. We ran into problems updating the PHP tooling in the past.

From my investigations pinning it to the last commit before the project requires a newer version of PHP doesn't work because symphony will report security errors and refuses to build?/finish correctly.

There is a PR on che-dockerfiles open to update to PHP 7.4 but the user still has to sign the eclipse contributor agreement.

I've built the image from that PR and tried it out and was able to successfully get install dependencies working

We've merged the PHP 7.4 update: eclipse-che/che-dockerfiles#253 but I can't find who's responsible for that repo so that we can get it released

It seems that repo is no longer used. The base image for the PHP devfile needs to be updated. Ideally it should use the upstream image as a base.

IIRC @amisevsk said we aren't using the upstream php image because there was some incompatibilities or something like that. Otherwise it would have been updated a long time ago
