Which version is that? I’m currently running 4.0.8 on the iHost, which is the newest. Is that the next beta?
Node.js is moving to 64bit only so it’s inevitable eventually. That add extra repository option will come in useful. The official Node Red docker will probably get removed. The last working version will probably need hosting elsewhere. There’s so many dockers of Node Red working on 32bit I’d bet the node Red forum has a link to a working version for years to come.
