I get the same all the time. OP reminded me to check today and Jetbrains toolbox had cached a lot of downloads that took up 42 GB in total. yarn folder with 2.3 GB. bazel folder with 15 GB (apparently used for building Anki),7 GB paru clones.
All in all it added up to 82 GB.
For private use? Hot take, but Arch. It’s easy to maintain and not easy to break at all. I think I spend zero time on maintenance other than running package updates. I only reinstall when I get a new computer.
(I say for private use only because you’ll be getting weird looks from people if you use arch on a server in a professional setting, and it might break if you try to update it after five years of not doing it since there aren’t any “releases” to group big changes - in practice I run arch on my home server too with no issues)
