Considering your budget of 200 GBP / 250USD, I would recommend laptops meant for school. There are plenty of refurbished laptops out there with a decent battery condition and overall state for sale around €100. Most of these machines aren’t more powerful than most entry level Chromebooks and often have a Pentium or Celeron CPU, but that’s a tradeoff you’ll have to make. Another advantage is that they usually come with a touch screen and decent display, which is nice if you’re out and about.
I can attest to that. It’s remarkable on how few distros updating through Discover actually works reliably. I always update through the terminal because at least that works. I’ve noticed this issue on Kubuntu (apt), Debian (apt), and OpenSUSE (zypper). I think these issues are related to the PackageKit integration.
