After multi-user install every command fails with SSL connect error (35)

[hasufell]

Describe the bug

On a multi-user install, every nix command throws SSL connect errors when trying to fetch from the cache. A single user install works fine.

$ nix-shell -p nix-info --run "nix-info -m"

error: Nix daemon disconnected unexpectedly (maybe it crashed?)

Steps To Reproduce

Steps to reproduce the behavior:

1. sh <(curl -L https://nixos.org/nix/install) --daemon
2. start a new shell
3. nix-shell -p nix-info --run "nix-info -m"

Expected behavior

Nix commands that fetch from the cache work.

Screenshots

Additional context

Nix was installed previously (also as multi-user). Due to a broken store, nix was uninstalled first according to the instructions at https://nix.dev/manual/nix/2.18/installation/uninstall.

The system is OpenSUSE Tumbleweed.

A single-user install works:

$ nix-shell -p nix-info --run "nix-info -m"
 - system: `"x86_64-linux"`
 - host os: `Linux 6.11.8-1-default, openSUSE Tumbleweed, noversion, nobuild`
 - multi-user?: `no`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.25.2`
 - nixpkgs: `/home/hasufell/.nix-defexpr/channels/nixpkgs`

Is this in some work/org environment that does or might have an ssl-intercepting proxy?

I am not certain if this is right since I haven't had to deal with one myself, but a single-user install might be picking up a cert bundle from an env that isn't available/set for the nix-daemon service.

No.

I have encountered the same error even when NIX_SSL_CERT_FILE=<CA_PATH> given on multi-user installation. After a removal and re-installation for single-user, it did work in a cooperate network.
