"cannot kill process with uid ..."

[Ed Falis <efalis@ewts.us>]

Newb, obviously.

Installed on foreign system (Pengwin on WSL-2).

Tried the installation of "hello" as a sanity check. It fails with:

guix install: error: cannot kill processes for uid `999' : failed with 
exit code 1

I've been stuck here about a week. The usual diagnosis seems to be that 
guix-daemon isn't running, but it is:

╭─falis@garuda-windows /home/falis  ‹system›
╰─$ ps -ef|grep guix
root      7013     1  0 13:31 ?        00:00:00 
/var/guix/profiles/per-user/root/current-guix/bin/guix-daemon 
--build-users-group=guixbuild
falis     8966  8898  0 14:27 tty3     00:00:00 grep --color=auto guix
╭─falis@garuda-windows /home/falis  ‹system›
╰─$

---

All of the usual package commands appear to fail the same way, and have 
no observable effect otherwise.

Any recommended lines of inquiry?

Thanks,
