This is strange and I have no clue what's going wrong here: All your
commands above work as expected.

Yes, I'm running out of disk space, but everything else works and the
nss-package isn't the biggest one. Currently 8 GiB left.

I built it locally, that worked. Now deleting it:

$ guix gc -D /gnu/store/32hy1jqkam201l7c4wg3bhxz4x5l5jy0-nss-certs-3.44.1

Then trying to fetch it:

~/guix/wt/nonfree [env]$ ./pre-inst-env  guix build nss-certs
0.2 MB will be downloaded:

This is on dd9c137b2c759f906d57b14fccff091994f274e8

Manually downloading seams to find the right hash:

$ wget -qO - https://ci.guix.gnu.org/nar/gzip/32hy1jqkam201l7c4wg3bhxz4x5l5jy0-nss-certs-3.44.1 |  gunzip | guix hash -

$ ls /gnu/store/*nss-certs-3.44.1* -d

I blamed that something about locales is wrong on berlin. Could it be
the case that on my side something with locales is wrong? In the build
daemon? I'm on Ubunutu+Guix, that might cause also some trouble? How
can I verify/check my locale-configs?

Thanks,
