I bought an old HP chromebook cheap on ebay that came with Zorin OS installed. It isn’t much, but just about manages to do what I need. The trouble is, Zorin seems kind of bloated and the Chromebook hasn’t got much memory. I don’t even have enough space to install updates.
I’m comfortable with running a pared-down OS that might be a better fit for a tired old Chromebook. What might work better than Zorin?
Maybe you can have a look at PostmarketOS, depending on the specific model your Chromebook is. They support some Chromebooks.
If it can run on old phones, it can run even better on Chromebooks I think, yes it is very lightweight but because musl app compatibility is bit more limited than glibc
