missing gems after docker_dev_update

[hmoffatt]

I have Canvas from 2022-02 for development running in Docker and I'd like to update it to the latest.

I've fetched the latest from git and I'm running docker_dev_update.sh, which fails with

docker-compose.override.yml exists, skipping copy of default configuration

The log ends with

I'm not sure what to do here as I think all the bundling is meant to happen inside the containers, ie I shouldn't have to install anything extra on the host. /home/docker does not exist on the host.

How can I fix this?

Thanks

There were all sorts of permission errors with the old checkout. Once I fixed those up, I found that the Postgres container had been updated from 12 to 14 with no way to migrate its data, so it wouldn't start.

So I gave up and installed it from scratch.
