🦉 Memory Leak

Don't think this is needed.

[ljharb]

Is there a reason not to do it?

[PeterDaveHello]

Same reason as #2537, unless we'd like to update this every 6 months, LTS version receives security updates longer enough.

[ljharb]

#2537 was updating to a dated release; this is updating to a specific version. I think it's valuable to upgrade frequently to actual versions, as long as doing so doesn't decrease which node versions are able to be installed.

[PeterDaveHello]

I think Ubuntu LTS versions with five years of support is saving us from frequent updates every six months required by non-LTS versions. This reduces the overhead of maintaining the environment. Given our development focus, the efficiency gained from less frequent updates outweighs the benefits of having the latest features, that we don't even needed. Therefore, sticking with LTS for our Docker base image is more beneficial in the long run.

[ljharb]

ah, 22.04 is LTS but 22.10 isn't? in that case, closing this makes sense.
