As @lorenzo mentioned this blocks migration because we try to create a session launcher with the image from your most recent commit of from your v1 project. Since the image for that project fails to build we cannot create a session launcher and we fail the migration.
If you want to use a standard image you can try this: ghcr.io/swissdatasciencecenter/renku/py-datascience-jupyterlab:2.6.2 It has jupyterlab and commonly used data science python packages.
So to get unstuck I think you should try the following:
- go to your v1 renku project ( Reproducible Data Science | Open Research | Renku )
- pin the image to be
ghcr.io/swissdatasciencecenter/renku/py-datascience-jupyterlab:2.6.2 - trigger a v1 → v2 migration (this should now succeed)
