@mauritsvanrees did 6.0.0a3 already depends on plone.volto? We are adding it later in the image.

Also, @avoinea @ericof @jensens @silviot Do we want to maintain all of them or deprecate (or just stop building) the images at some point (and rely on the historic from registry).

Not yet. We should probably do that for the next alpha (or first beta). The collective.folderishcontenttypes dependency is gone, which was the biggest blocker for this, IIRC.
PR is already here: plone/Plone#20
But it would be good to fix some coredev tests first, which appear when we add plone.volto to the test eggs: plone/buildout.coredev#764

BTW, pip version 22 is out, which means we no longer need to use the deprecated resolver option.
But it gives a problem with buildout so it may be too much trouble to update currently.

LGTM

[jensens]

pip 22 works fine in a3. I use it in a project (with mxdev 2)

[avoinea]

@jensens Should we then upgrade?

plone-backend/6.0/6.0.0a3/Dockerfile.python39

Lines 19 to 20 in c066c73

	ENV PIP_PARAMS="--use-deprecated legacy-resolver"
	ENV PIP_VERSION=21.3

Yes, pip 22 works fine with Plone and without the legacy resolver!
But it should reflect in buildout.coredev pip pins (versions.cfg/requirements.cfg) as well then, right?

I tried latest pip in coredev a few days ago, but it failed.
I updated my WIP PR with the newest versions, but still fails.
Needs a fix in buildout

BTW, pip 22.0.3 is out with a another fix by me for the new resolver. Should only matter in corner cases.

[jensens]

ah, buildout, I use it with pip only in some projects and that works.
