![]() On a systemd-based Linux distribution: If the user has previously had multi-user Nix installed on the system, removed it and then reinstalled multi-user Nix again the old nix-daemon.service will still be running when `scripts/install-systemd-multi-user.sh` tries to start it which results in nothing being done and the old daemon continuing its run. When a normal user then tries to use Nix through the daemon the nix binary will fail to connect to the nix-daemon as it does not belong to the currently installed Nix system. See below for steps to reproduce the issue that motivated this change. $ sh <(curl https://nixos.org/nix/install) --daemon $ sudo rm -rf /etc/nix /nix /root/.nix-profile /root/.nix-defexpr /root/.nix-channels /home/nix-installer/.nix-profile /home/nix-installer/.nix-defexpr /home/nix-installer/.nix-channels ~/.nix-channels ~/.nix-defexpr/ ~/.nix-profile /etc/profile.d/nix.sh.backup-before-nix /etc/profile.d/nix.sh; sed -i '/added by Nix installer$/d' ~/.bash_profile $ unset NIX_REMOTE $ sh <(curl https://nixos.org/nix/install) --daemon └$ export NIX_REMOTE=daemon └$ nix-env -iA nixpkgs.hello installing 'hello-2.10' error: cannot connect to daemon at '/nix/var/nix/daemon-socket/socket': No such file or directory (use '--show-trace' to show detailed location information) └$ sudo systemctl restart nix-daemon.service └$ nix-env -iA nixpkgs.hello installing 'hello-2.10' these paths will be fetched (6.09 MiB download, 27.04 MiB unpacked): /nix/store/2g75chlbpxlrqn15zlby2dfh8hr9qwbk-hello-2.10 /nix/store/aag9d1y4wcddzzrpfmfp9lcmc7skd7jk-glibc-2.27 copying path '/nix/store/aag9d1y4wcddzzrpfmfp9lcmc7skd7jk-glibc-2.27' from 'https://cache.nixos.org'... copying path '/nix/store/2g75chlbpxlrqn15zlby2dfh8hr9qwbk-hello-2.10' from 'https://cache.nixos.org'... building '/nix/store/w9adagg6vlikr799nkkqc9la5hbbpgmi-user-environment.drv'... created 2 symlinks in user environment |
