With portage-3.0.65, I'd forgot to setup getuto first, and got this:

I think the error is mostly fine but I was expecting it to be prettified like with eerror (see bug 927632).

[Comment 1 Sam James 2024-07-20 01:45:35 UTC]

Looks like we prettify it in lib/_emerge/BinpkgPrefetcher.py but not in lib/_emerge/Scheduler.py, so BinpkgPrefetcher vs BinpkgFetcher?
